Question

The Copper Chloride solution used in the investigation contained 300 grams per dm3 of solid CuCl2 dissolved in 1dm3 of water.

Answer 1

Answer:

The mass of solid copper chloride used in each experiment=15 g

Explanation:

We are given that

Mass of copper chloride in solution=300g/dm3

Volume of solution used in each experiment=50 cm3

We have to find the mass of solid copper chloride used in each experiment.

$1cm^3=0.001 dm^3$

$50cm^3=0.05 dm^3$

1 dm3 contained solid copper chloride=300 g

0.05 dm3 contained solid copper chloride=$300\times 0.05$g

0.05 dm3 contained solid copper chloride=15 g

Hence, the mass of solid copper chloride used in each experiment=15 g
