a. 195.06 g
elaborate your question on letter b, i've got the answer on that one by using the formula of percent weight by weight (%w/w)
%w/w = weight solute/weight volume
a. 5.35 moles of solute
b.0.00616 mol sucrose
step 1: list all given variables
Volume = 1.25 L
Molarity = 4.28 M
Step 2: calculate the unknown
Molarity= mole of solute/Liter of solution
Mole of solute = molarity x liter of solution
= 4.28 M x 1.25 L
= 5.35 moles of solute
step 1: list all given variables
mass of solution = 85.3 g
mass % sucrose = 2.47 %
step 2: calculate the unknown
2.47%×1/100×85.3g×(1 mol sucrose)/(342.2965 grams sucrose)=0.00616 mol sucrose

Alcohol:For alcoholic beverages, "alcohol" is actually ethanol.Petrol : Ethanol burns to generate carbon dioxide and water and can be used as a fuel on its own or in petrol (gasoline) mixtures. "Gasohol" is a mixture of petrol / ethanol containing roughly 10-20% ethanol.
Because ethanol can be produced by fermentation, this is a useful way to reduce fuel imports for countries without an oil industry.As a Solvent: The use of ethanol as solvent is common. It is relatively safe, and can be used to dissolve most water-insoluble organic compounds. For starters, it is used in various perfumes and cosmetics.
- It is a flammable liquid that is colorless, unstable and the simplest and smallest ketone. Acetone is formed in the human body and disposed of through normal processes of metabolism. It usually occurs in the blood and urine.Solvent: For many plastics and some synthetic fibers, acetone is used as a strong solvent.Medical and Cosmetic purposes: Acetone is used in a number of general medical and cosmetic applications and is also identified in food additives and food packaging as an ingredient as well as in nail polish remover. Dermatologists use alcohol acetone to peel dry skin for acne treatment.Home Use: For cleaning agents such as the remover for nail polish, acetone is often the primary component. Acetone is a part of a superglue remover that removes glass and porcelain residues easily. Make-up artists use acetone to extract skin adhesive from wig and mustache netting by immersing the product in an acetone tub, then scraping the layer of soft glue with a stiff brush.
Liquefied Petroleum GasCooking: For economic reasons, safety or because it is the preferred fuel source, LPG is used for cooking in many countries.Heating: LPG can provide an alternative to electric heating, heating oil, and kerosene, particularly in Europe and rural parts of many countries. LPG is most widely used in areas where piped natural gas is not directly accessible.Refrigeration: LPG is instrumental in supplying off - the-grid heating, normally through a refrigerator for gas absorption.
Formaldehyde is an important chemical building block in the manufacture of hundreds of items that enhance daily life. In the final products which customers use, formaldehyde remains little, if any.Construction: Formaldehyde-based resins are used in the manufacture of structural and fabricated wood products that are commonly used in paneling, countertops, cabinetry, hardware, worktops, staircase systems, wooden floors, drywall, reinforcing beams and joists and many other household furniture and structures.Health Care: In the production of vaccines, anti-biotic medications and hard-gel capsules, formaldehyde has a long history of safe use. Of example, in producing the influenza vaccine, formaldehyde is used to inactivate viruses so that they do not cause disease, like the influenza virus.Automobiles The engineering of formaldehyde helps to make cars lighter and more energy efficient. Interiors are also resin-based which benefits from using formaldehyde.
A smooth, solid wax that is pure and colorless. It is made of hydrocarbons that are saturated.Also, paraffin wax is applied to the hands and feet cosmetically. The wax is a natural emollient that helps make the skin smooth and supple. This restores moisture when applied to the skin and helps to improve the skin's moisture levels following completion of the procedure.
It can also aid in opening pores and eliminating dead skin cells. This can help freshen the skin and feel better.Therapy. This serves as a form of heat therapy and can help to increase blood flow, relax muscles and decrease the rigidity of the joint. It can help with the following: rheumatoid arthritis, osteoporosis, fibromyalgia.
Diesoline:Diesoline is a distillate fuel used in diesel engines and industrial applications (on-road and off-road) such as marine diesel machinery, direct-driven engine such as pumps and compressors, boilers, furnaces, gas turbines and other combustion equipment.
Grease:Grease is typically used for: machines operating intermittently or in long-term storage. Because grease remains in place, a lubricating film may form immediately.
Lubricating Oil:Lubricating oil is a class of oils used to reduce friction, heat, and wear between mechanical components that are in contact with each other. For motor vehicles, where it is commonly known as motor oil or transmission fluid, lubricating oil is used.
In general, most of these items are used in the industrial field, that benefits all consumers.
