Question

What is the percent by mass in which 82.0 g of NaCl is dissolved in 372 grams of
water?

Answer 1

Answer:

Explanation:

solute= NaCl  solvent = water

mass %=( mass of the solute/total mass of solution) × 100

           =[ 82.0/(82.0+ 372)] × 100

           =(82.0/454) × 100

           = 0.180 × 100

          = 18 %

I hope u got it
