Question

What is the mass percent of a solution that contains 10 g of NaCl in 90 g of water?

Answer 1

Answer:

Conc. of solution in terms of w/w% = weight of solute/weight of solution × 100 = 10g/100 g × 100 = 10%

Note:

Here, Mass of solution = mass of solute + mass of solvent = 90 + 10 = 100 g
