Question

weight of the 1×10^22 molecules of CuSO is​

Answer 1

4.146 g

Answer:

mark as a brainlist

Explanation:

Number of molecules = 1 x 10^22 molecules

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

Hence,

Weight of 1 × 10^22 molecules =

(249.72/6.023 ×10^23)× 1 × 10^22 = 4.146 g
