mols HCl used = M x L = ?
Now use the coefficients in the balanced equation to convert moles HCl to moles CaCO3. moles HCl x (1 mole CaCO3/2 moles HCl) = ?moles HCl x 1/2 = xx moles CaCO3.
grams CaCO3 = moles x molar mass and convert to mg.
A rolaids tablet contains calcium carbonate which neutralizes stomach acid. If rolaids tablet neutralizes 42.15 mL of 0.320M hydrochloric acid, how many milligrams of calcium carbonate are in a Rolaids tablet
CaCO3 + 2 HCl ------> CaCl2 + H2O + CO2
Pls show steps
