What is the mass in grams of 0.803 mol of KCIO

Answer 1

First, find the molar mass (molecular weight) of KClO

K = 39.1 g

Cl = 35.5 g

O = 16.0 g

Total = 90.6 g/mol

So, if ONE mole = 90.6 g, then 0.803 moles is equal to how many grams?

Use dimensional analysis: 0.803 mols x 90.6 g / mol = 72.8 g

Or use proportionality: 1 mol / 90.6 g = 0.803 mol / x g and x = 72.8 g
