Question

1. a solution contains 60 g of sugar in 480 g of water. calculate the concentration of solution in terms of mass by mass percentage of the solution

Answer 1

mass of solute = 60g
mass of solvent = 480g
mass of solution = 60+480 = 540g

concentration by mass percentage
= mass of solute/mass of solution * 100
$60 \div 540 \times 100$

$100 \div 9 = 11.1\%$

Answer 2

60/480+60

60/540

=0.11
