Calculate the relative formula mass of Zn(NO3)2. Round your answer to the nearest whole number?

The relative formula mass of Zn(NO₃)₂ is 189.38g. How do we calculate the mass of any compound? Molecular mass of any formula of compound will be calculated by adding the molar mass of each atoms present in the given compound. Molecular mass of Zn(NO₃)₂ = Sum of the molar mass of Zinc, nitrogen and oxygen atoms. Molecular mass of Zn(NO₃)₂ = 65.38g/mol + 2(14g/mol) + 6(16g/mol) = 189.38g Hence the required mass of Zn(NO₃)₂ is 189.38g.
