(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

mixture of CaCO3 and CaO m=0.656 g, heated to produce CO2. After heating, only CaO solid remains and it weighs 0.485 g.

Assuming all the CaCO3 decomposed to CaO and CO2, calculate the mass percent of CaCO3 in the original mixture.

2. Relevant equations

3. The attempt at a solution

I have no clue how to start this off. The answer is 59.3
