Calculate the mass of 5.3 moles of chloric acid (hcio3). explain the process or show your work by including all values used to determine the answer

5.3 moles times the molar mass of HClO3 will give you this. The molar mass is equal to 84.46 grams/mole. This can be calculated by summing the atoms and their masses. Hydrogen - 1 g/mole. Chloride - 35.45 g/mole. Oxygen - 16 g/moles times 3 since there are 3 atoms. This gives the molar mass. The final answer would be 447.64 grams.

Here is how I solved it:

Equation: 5.3 moles x molar mass of HCIO3  

Find Molar Mass: 1 g/mole + 35.45 g/mole + 16 g/mole x 3 = 84.45 g/mole  

5.3 moles x 84.45 g/mole = 447.64 Grams

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
