Question

a student has a piece of copper sulphate crystal .explain the method of calculating the number of CuSO4 molecules in the crystal​

Answer 1

Explanation:

find out the mass of sample taken ,find out molecular mass (63.5+32+4×16)

find number of moles which is given mass /molecular mass .

in 1mole we have Avogadro no (6.6×10^23) of molecules

so use unitary method to find out no of molecules
