## Question:

A solution is made containing 11.2 g of sodium sulfate per 95.0 g of water. What is the weigh / weight % or percent by mass of the solute?

## Answer:

Answer: –

**10.5% is the Weight / weight % or percent by mass of sodium sulfat**e

Explanation: –

Mass of sodium sulfate = 11.2 g

Mass of water = 95.0 g

**Total mass of the solution = Mass of sodium sulfate + Mass of water**

= 11.2 + 95.0 = 106.2 g

**Weight / weight % or percent by mass of the solute = (Mass of sodium sulfate / Total mass of the solution) x 100**

=

= 10.5 correct to 3 significant figures.

They may hopefully help the student handle the question by using the questions and answer examples. You can then have a discussion with your classmate and continue the school learning by studying the subject alogside each other.
