Question

The reaction of limestone with hydrochloric acid is

CaCO3+2HCl⟶CaCl2+CO2+H2O

If the reaction produced 13.5 g CO2, how many grams of HCl reacted?

despertate help needed, 61.3 g is wrong
thank you!

Answer 1

find moles of CO2 ... 13.5 / 44.01

moles of HCl is twice moles CO2 ... 2 * 13.5 / 44.01

grams HCl equals moles times molar mass ... (27/44.01) * 36.46 g

Answer 2

thank you so much! that was correct!
