In chemistry, moles are the measurement units that are used to estimate the small entities of the atoms or the molecules. Moles are calculated as:
Moles = mass ÷ molar mass
We know,
The molar mass of calcium = 40 gm/mol
The mass of calcium = 13.95 gms
Moles of calcium are calculated as:
Moles = 13.95 ÷ 40
= 0.348 moles
Therefore, in 13.95 gms 0.348 moles of calcium is present.
