Find the molar mass of calcium carbonate by calculation.

Open in App

Solution

Molar mass- The amount of molecules or atoms or compounds present in one mole of a substance is given by Molar mass.
SI unit for Molar mass is $g / m o l .$
Formula to calculate the molar mass of Calcium Carbonate $({CaCO}_{3})$
$M o l e c u l a r m a s s o f t h e C a C O_{3} = A t o m i c m a s s o f t h e C a + A t o m i c m a s s o f t h e C + 3 (a t o m i c m a s s o f t h e o x y g e n)$
Atomic Mass of Calcium= $40 g / m o l$
Atomic Mass of Carbon = $12 g / m o l$
Atomic Mass of Oxygen = $16 g / m o l$
The molecular mass of $C a C O_{3} = (40 + 12 + 3 \times 16)$ g/mol
Molecular mass of $C a C O_{3} = 100 g / m o l$

Hence, the formula mass of Calcium Carbonate $({CaCO}_{3})$ is $100 g / m o l$
