Question

A solution contains 60 g of common salt in 320g of water . Calculate the concentration in term of mass by mass percentage of the solution?

Answer 1

Mass of solute - NaCl =60gm

Mass of solvent - water =320gm

Mass of solution =(60+320) gm

=380gm

Concentration in terms of Mass by mass percentage =mass of solute /mass of solution *100

=60/380*100%=15.78%

Hope this help. Mark as brainliest please

Answer 2

Answer:Here is the answer. Hope you like it
mass of solute(salt) - 60g
Mass of solvent(water)- 320g
Solution = solute + solvent
= 60 + 320
= 380g
Mass by mass percentage.= Mass of solute ÷ mass of solution × 100
= (60 ÷ 380) × 100
= 15.7894%
