Question

Q.40g of common salt is dissolved in 320g of water.The mass percentage of salt is

Answer 1

Answer:

11.1%

Explanation:

Mass (solute) = 40 gram

Mass (solvent) = 320 gram

Mass (solution) = Mass (solute) + Mass (solvent)

                       = 40 gram + 320 gram

                       = 360 gram

∴ Mass % (solution) = [ Mass (solute)/Mass (solvent)] × 100

                               = [40/360] × 100

                               = 11.1 %

Hope it is helpful
