Zinc nitrate has 1 molecule of zinc (Zn), 2 molecules of nitrogen (N) and 6 molecules of oxygen (O).
Calculate the molecular mass of zinc nitrate by adding the molecular weights for all molecules in the compound.
Here are the molecular weights for each element:
Zn=65.38 g/mol
N=14.01 g/mol
O=16.00 g/mol
The molecular weight of zinc nitrate is then: 1*(65.38)+2*(14.01)+6*(16.00)=189.40 g/mol.
Using a conversion formula to calculate moles of zinc nitrate:
