Question

How much copper can be obtained from 100gm cooper sulfhate?

Answer 1

Answer:

1 mole of CuSO4 contains 1 mole of copper. 159.5 g of CuSO4 contains 63.5 g of copper.

Answer 2

Answer :

• Amount of Cu that can be obtained from 100g CuSO₄ = 39.81 g.

Step-by-step explanation:

Given that,

• Total mass of CuSO₄ = 100 g.

Also,

• Atomic mass of Cu = 63.5 amu.

$\hrulefill$

1 mole of CuSO₄ contains 1 mole (63.5 g) of Cu

Now, molar mass of CuSO₄ =

⇒ 63.5 + 32 + 4 × 16

⇒ 159.5 g/mol

∴ 159.5 g of CuSO₄ contains = 63.5 g of Cu

Then, 100 g of CuSO₄ contains =

$\implies\rm{\dfrac{63.5}{159.5}\times{}100}$

$\implies\bold{39.81\:g.}$
