Calcium carbonate reacts with citric acid to yield calcium citrate. It is highly soluble in water and acids and has a higher bioavailability rate (de Paula et al., 2014). It contains 21% calcium and provides around 67% absorption (Oliveira et al., 2013). Besides, calcium hydroxide, also...

I would start with a balanced chemical equation, and the ideal gas laws. The gas laws are approximations, and not really accurate for the quantities from a production facility. But its a good way to start. Why not try it out calculating this WA, with say a kilo of reactants and see ...
