Question

What mass of a 4.00% NaOH solution by mass contains 15.0 g of NaOH?

Answer 1

375 grams of 4% NaOH solution contains 15 grams NaOH

Step-by-step explanation:

Given 4% solution of NaOH = 4g NaOH/100 g Solution

=> 4g NaOH/100g Soln = 15 g NaOH / X

=> X = 15 g NaOH (100 g Soln) / 4 g NaOH = 375 grams Soln contains 15 g NaOH.
