Understanding Molar Mass

The molar mass of a compound is the mass of one mole of that substance. It is calculated by summing the atomic masses of all the atoms in the compound’s formula. For barium hydroxide, the molar mass is determined by adding the atomic masses of barium (Ba), oxygen (O), and hydrogen (H).

Calculating the Molar Mass of Barium Hydroxide

To calculate the molar mass of barium hydroxide (Ba(OH)₂), we need to know the atomic masses of the constituent elements:

Barium (Ba): approximately 137.33 g/mol
Oxygen (O): approximately 16.00 g/mol
Hydrogen (H): approximately 1.01 g/mol

The formula for barium hydroxide is Ba(OH)₂, which means it contains one barium atom, two oxygen atoms, and two hydrogen atoms. The molar mass is calculated as follows:

Molar mass of Ba(OH)₂ = (1 × 137.33 g/mol) + (2 × 16.00 g/mol) + (2 × 1.01 g/mol)

Molar mass of Ba(OH)₂ = 137.33 g/mol + 32.00 g/mol + 2.02 g/mol

Molar mass of Ba(OH)₂ = 171.35 g/mol

Therefore, the molar mass of barium hydroxide is approximately 171.35 g/mol.
