Question

molar mass of Zn (NO₃)₂ is

Explain the answer​

Answer 1

Answer:the molar mass of zinc nitrate is approximately 189.39 grams per mole. The chemical formula for zinc nitrate is Zn(NO3)2.

Explanation:

Answer 2

Answer:

189.40 g/mol

Explanation:

Since, molar mass is of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles.

Here are the molecular weights for each element in Zn(NO₃)₂:

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.
