## What is the molecular mass of Cao?

56.0774 g/mol
Calcium oxide/Molar mass

What is the molecular mass of CaCO3 Class 9?

In order to calculate the molar mass of $CaC{O_3}$ we have to summate the individual molar mass of each element. Since there are 3 moles of $O$, its molar mass is computed as $3 \times 16 = 48$. Hence the molar mass of $CaC{O_3}$$:40 + 12 + 48 = 100g/mol$. So, Option D is the answer.

### What ion is CaCO3?

Calcium carbonate
Calcium carbonate (CaCO3) has ionic bonding between calcium ion Ca2+ and a polyatomic ion, CO2−3, but within the carbonate ion (CO32-), the carbon and oxygen atoms are connected by covalent bonds (shown above).

### Is CaCO3 a base?

Answer: calcium carbonate is a salt, it is neither acid nor base.

## What is the structural formula of CaCO3?

Formula and structure: The chemical formula of calcium carbonate is CaCO3 and its molar mass is 100.1 g/mol. It is a salt made of the bivalent calcium cation (Ca2+) and the bidentate carbonate anion (CO32-), in which the carbon is attached to two oxygen atoms through single bonds and one oxygen atom through a double bond.

How do you calculate the molecular mass?

Molecular mass may be calculated by taking the atomic mass of each element present and multiplying it by the number of atoms of that element in the molecular formula. Then, the number of atoms of each element is added together.
