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 sulfate
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.
