Question

Calculate the number of mole in 75g of HCL

Answer 1

Question:

Calculate the number of mole in 75g of HCl.

Soution:

Mass of Hydrogen = 1 amu

Mass of Chlorine = 35.5 amu

Molar mass of HCl = 1 + 35.5 = 36.5 g/mol.

We know,

Number of moles = Given mass / molar mass

Number of moles = 75 / 36.5 moles

Number of moles = 2.05 moles
