calculate the masses of each substance formed when 10g of CaCO3 reacts with excess HCl

so far I've found the ratio between the substances but from then on, I'm lost

1 answer

10g CaCO3 = (10/100)mole = 0.10 mole CaCO3

CaCO3 + Excess HCl =>CaCl2 + CO2 + H2O
0.10-mol CaCO3 + <HCL> => 0.10-mol CaCl2 + 0.10-mol CO2 + 0.10-mol H2O
=> 0.10(111)g CaCl2 + 0.10(44)g CO2 + 0.10(18)g H2O
=> 11.1g CaCl2 + 4.4g CO2 + 1.8g H2O
