Question

what is the molar mass of kclo₃?
○ 106. 55 g/mol
○ 122.545 g/mol
○ 110.98 g/mol
○ 138.55 g/mol

Explanation:

Step1: Identify atomic masses

Atomic mass of K (Potassium) is approximately 39.0983 g/mol, Cl (Chlorine) is approximately 35.453 g/mol, and O (Oxygen) is approximately 15.9994 g/mol.

Step2: Calculate molar mass of \(KClO_3\)

Molar mass = (Atomic mass of K) + (Atomic mass of Cl) + 3*(Atomic mass of O)
