Ca=40
N=14x2=28
O=6x16=96
molar mass=40+28+96
molar mass=164g/mol

Answer:

Molar mass = 164 grams per mol

Explanation:

The compound above is calcium nitrate represented as Ca(NO3)2. The molar mass of the compound can be calculated from the atomic mass of each atom present in the compound.

Atomic mass of calcium = 40 g

Atomic mass of nitrogen  = 14 g

atomic mass of oxygen = 16 g

Ca is 1 mole = 40 grams

Nitrogen is 2 moles = 14 × 2 = 28 g

oxygen is 6 moles = 16 × 6 = 96 g

The sum = 40 + 28 + 96 = 164 grams per mol
