A copper sulfate solution contained 0.100 moles of copper sulfate dissolved
in 0.500 dm3 of water.
calculate the mass of copper sulfate in 30.0 cm3 of this solution.
relative formula mass (mr): cuso4 = 159.5

Respuesta :

The mass copper sulphate CuSO₄ in 30ml solution is 957.6g.

What is the solution?

A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.

To determine the mass of copper sulphate in the given solution, compare both the molarity given:

M₁V₁=M₂V₂

[tex]\frac{n_1}{V_1} =\frac{n_2}{V_2}[/tex]

0.1/0.5=n₂/30         cm³=ml

n₂=6 moles

6×159.5=957.6g

Multiply the calculated moles with the relative mass/molecular mass to get the mass of CuSO₄.

Hence, the mass of CuSO₄ is 957.6g
