Problem: Consider this question: What mass of a concentrated solution of nitric acid (68.0% HNO3 by mass) is needed to prepare 400.0 g of a 10.0% solution of HNO3 by mass? (a) Outline the steps necessary to answer the question. (b) Answer the question.

FREE Expert Solution

We are being asked to determine the mass of a concentrated solution of nitric acid (68.0% HNO3 by mass) is needed to prepare 400.0 g of a 10.0% solution of HNO3 by mass


Recall that mass percent is given by

mass percent = mass componenttotal mass×100


We are going to do the following steps:

Step 1: Calculate the mass component of the dilute solution

Step 2: Calculate the total mass of the concentrated solution
