4.8 g of zinc was added to the solution containing copper sulfate. What kind of salt did you get? Calculate its mass.

The mass of zinc is 4.8 g.

Determine the mass of the resulting salt.

First, you need to write down the reaction equation.

CuSO4 + Zn = ZnSO4 + Cu.

Consequently, a salt is formed called zinc sulfate.

First, we calculate the molar mass of zinc and zinc sulfate.

M (Zn) = 65 g / mol.

M (ZnSO4) = 65 + 32 + 16 * 4 = 161 g / mol.

Next, using the reaction equation, we determine the mass of zinc sulfate.

4.8 g zinc – x g zinc sulfate

65 g / mol zinc – 161 g / mol zinc sulfate

X = 161 * 4.8: 65 = 11.2 g.

Answer: the mass of the salt obtained is 11.2 g.
