Question

You have 28.94 grams of solid sodium nitrate. You want to create a solution that has a %m/v of 38.5%. What should your final solution volume be to achieve this concentration, assuming you dissolve all of your sodium nitrate?

Answer 1

Ans 1.

38.5 % m/v has 38.5 g of sodium nitrate dissolved in 100 ml of solution .

if 28.94 g of solute is 38.5% , so the final volume of solution will be (28.94 x 100) / 38.5

= 75.17 ml

So the final volume of solution must be 75.17 ml
