Question

The weight of 1 x 1022 molecules of Cuso .5H,O is
​

Answer 1

Answer:

Number of molecules = 1 x 10*22molecules

Molecular mass of CuSO4.5H2O = 249.72 g/mol

We know that,

1 mole of CuSO4.5H2O contains 6.023 x 10^23

molecules

Therefore,

6.023 x 10^23

molecules have a mass of 249.72 g

Hence,

Weight of 1 × 1022 molecules = 249.72 6.023 × 1023× 1 × 1022 = 4.146 g
