Homework Answers
a) Mass of sucrose = moles×molar mass
= 0.075×342 (molar mass of sucrose = 342 g/mol)
= 25.65 g
b) Molarity = moles×1000/volume (in ml)
= 0.075×1000/150
= 0.5 M

When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid (also known as a solute) in a solvent to form a solution, the solute becomes evenly distributed throughout the solution and we need to know how many moles of solute are present in a particular volume of solution. pt. 1 A solution is created by dissolving 10.0 grams of ammonium chloride in...

21. A student correctly determines that 17.1 grams of sucrose are needed to make 50 mL of a 1 M sucrose solution. When making this solution in lab, the student measured 50 mL of water and massed 17.1 grams of sucrose. The student then mixed the two together into a new beaker. The student's resulting solution was not 1 M sucrose as intended. After the student mixed sucrose and water, the resulting solution was poured into a graduated cylinder and...

The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 795 mL of a 40.0% (w/v) sucrose solution? sucrose MISS Use the quantities to show how each calculation is made.
