Need someone to confirm my answer to Chem/Math problem.

I don't have the answer key, so I need someone to check and tell me if I got it right. I probably got it wrong, but there is a slim chance I might have gotten this one right. And please check if I got the rounding off of the numbers right because I am sort of unsure of the rules (chemistry rules in rounding off digits).

Problem is:

"What mass of lime CaO can be obtained by heating 125 kg of limestone that is 95.0% by mass CaCO3"

"CaCO3 = CaO = CO2"

- Note: the numbers 3 and 2 are subscript and indicate the amount of Oxygen.

The answer I get is 70100g/mol or 7.01x10^4
