See no of moles =given wt/molar wt=no of molecules/avogadro number
.so w/250=10^22/6×10^
w=250/60=4.16 g .

The mass of 1 x 1022 molecules of CuSO₄.5H₂O isa)41.59 gb)...
Explanation:
Given:
Number of molecules of CuSO.5H2O = 1 x 10^22
Formula:
Molar mass of CuSO4.5H2O = 249.68 g/mol
Calculation:
1 mole of CuSO4.5H2O contains 6.022 x 10^23 molecules.
Therefore, the molar mass of CuSO4.5H2O = 249.68 g/mol
This means that 1 molecule of CuSO4.5H2O weighs 249.68/6.022 x 10^23 g.
Now, for 1 x 10^22 molecules:
(1 x 10^22) x (249.68/6.022 x 10^23) = 4.159 g
Therefore, the mass of 1 x 10^22 molecules of CuSO4.5H2O is 4.159 grams, which corresponds to option 'C'.
Given:

Therefore, the molar mass of CuSO4.5H2O = 249.68 g/mol
This means that 1 molecule of CuSO4.5H2O weighs 249.68/6.022 x 10^23 g.
Now, for 1 x 10^22 molecules:
(1 x 10^22) x (249.68/6.022 x 10^23) = 4.159 g
Therefore, the mass of 1 x 10^22 molecules of CuSO4.5H2O is 4.159 grams, which corresponds to option 'C'.
