Question

To make 2% copper sulphate solution grams of copper sulphate is dissolved in 100 ml of water....how many grams needd​

Answer 1

Thus 2 grams of copper sulfate is required.

Given that:

• According to the question statement, we have to prepare a 2% solution of copper sulfate i.e CuSO₄ in 100ml of water.
• For this, we need to calculate the number of grams of copper sulfate needed.

Solution:

• The formulas of weight volume percentage is as under;
• %W/V = 2%
• Volume (V) = 100ml.
• % weight/volume = 2% / 100 = 2 grams
• Weight of copper sulfate = 2 grams.
• Therefore, two grams of copper sulphate are required to make 2% CuSO₄ solution in a volume of 100ml
