Gas karbon dioksida (CO2) dapat diperoleh melalui reaksi berikut:
CaCO3(s) + 2HCl(aq) --> CaCl2(aq) + H2O(l) + CO2(g)
Dalam suatu reaksi antara 100 gram CaCO3 dengan larutan asam klorida ternyata dihasilkan gas CO2 sebanyak 19.04 liter (diukur pada keadaan STP). Jika Ar Ca = 40, C = 12, dan O = 16, rendemen hasil reaksinya adalah......
