solve this question aand explain me ??​

Answer 1

According to the mole concept,

1 mole of every substance= it's molecular weight= avogadro number of molecules.

The molecular mass of CuSO4.5H2O = 249.5 g approx., which means ,

6.022 *10^23 molecules of it has mass= 249.5g

So, by unitary method, 10^22 molecules of it has mass= 249.5/60.22 g = 4.14g
