Question

A solution contains 80g of common salt in 500g of water. Calculate the concentration in terms of mass by mass percentage of solution

Answer 1

solute is 80g

solvent is 500g

concentration is equal to solute /solvent multiplied by 100

let concentration be x

$x = 80 \div 500 \times 100$

$x = 80 \div 5 = 16$

16% is the answer .
