Question

Calculate mass of HCl in when 40gm CaCO3 react with HCl in the reaction.
CaCO3 + HCl ---> CaCl2 + CO2 + H2O

Answer 1

Answer:

28.4 grams

Explanation:

first balance the equation.. so u will get, 1 mole caco3 reacting with 2 mole hcl.. and we have 40 GRAMS caco3 ..so first find the moles of caco3 and later by unitary method, calculate the mole of hcl w.r.t caco3.. and finally convert it in grams
