Metal carbonates react with acid to produce a salt, water, and carbon dioxide gas as seen in the reaction below. Na2CO3(s)+2HCl(aq)→2NaCl(aq)+CO2(g) +H2O(l)

If 1.45 g of Na2CO3 reacts with an excess amount of HCl, what volume of CO2 will be produced at STP?

Achemist has dissolved a certain substance in water. the chemist knows that more of the substance could be dissolved into the water before it stops dissolving. therefore
