Calculate the w/v percentage of each of these solutes:
A. 623 mg of casein in 15 mL of milk
B. 74 mg of vitamin C in 250 mL of orange juice
C. 3.25 g of sucrose in 186 mL of coffee
Expert Answer
Part-a: 623 mg of casein in 15 mL of milk
Formula to calculate w/v percentage :
w/v percentage = mass of solute / volume of solution X 100
Mass of solute = 623 mg
Volume of milk = 15 mL
Substitute the known values in the formula,
(623 X 10-3 g /15 mL) X 100 = 4.153 %
B. 74 mg of vitamin C in 250 mL of orange juice
Formula to calculate w/v percentage :
w/v percentage = mass of solute / volume of solution X 100
Substitute the...
