Consider this question: what mass of concentrated solution 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

The mass of concentrated nitric acid solution required is 58.82 g

Explanation:

To calculate the mass of concentrated solution, we use the equation:

where,

are the concentration and mass of concentrated solution.

are the concentration and mass of diluted solution.

We are given:

Putting values in above equation, we get:

Hence, the mass of concentrated nitric acid solution required is 58.82 g

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.
