Question

What weight of cuso4.5h2o must be taken to make 0.5?

Answer 1

Answer ⇒ The mass of CuSO₄.5H₂O required to make its 0.5 moles is 124.75 g.

Question is little incomplete. Let me complete it.

What weight of CuSO₄.5H₂O must be taken to make 0.5 moles?

Explanation ⇒

Molar mass of Copper sulphate crystals = 63.5 + 32 + 16 × 4 + 5 × 18

= 95.5 + 64 + 90

= 249.5 g/mole.

Now, Using the formula,

No. of moles = mass/molar mass

∴ 0.5  = mass/249.5

∴ mass = 249.5 × 0.5

∴ mass = 124.75 g.

Hence, the mass of CuSO₄.5H₂O required to make its 0.5 moles is 124.75 g.

Hope it helps.
