Question

The chemical formula for zinc nitrate is
Zn(NO3)2
Calculate the molar mass of zinc nitrate.
Round your answer to l decimal place.

Answer 1

To calculate the molar mass of zinc nitrate (Zn(NO3)2), we need to first determine the molar mass of each element present and then calculate the total molar mass.

Molar mass of Zn = 65.38 g/mol
Molar mass of N = 14.01 g/mol
Molar mass of O = 16.00 g/mol

Now, let's calculate the molar mass of zinc nitrate:
Molar mass = (molar mass of Zn) + 2*(molar mass of N) + 6*(molar mass of O)
Molar mass = 65.38 + 2*(14.01) + 6*(16.00)
Molar mass = 65.38 + 28.02 + 96.00
Molar mass = 189.40 g/mol

Therefore, the molar mass of zinc nitrate (Zn(NO3)2) is 189.40 g/mol.
