Correct Answer - Option 1 : 164.1
The correct answer is 164.1.
- The molar mass of calcium nitrate Ca(NO3)2 is 164.1
The molar mass of calcium nitrate Ca(NO3)2 can be calculated as follows:
- It contains one atom of calcium, two atoms of nitrogen, and six atoms of oxygen.
The molecular weight can be calculated as:
- Ca: 1 x 40.1 = 40.1
- N: 2 x 14.0 = 28
- O: 6 x 16.0 = 96
- Adding above values i.e, 40.1 + 14 + 16 = 164.1
- Hence, the molar mass of Ca(NO3)2 is 164.1 g/mol.
