2HCl + CaCO3 ==> CaCl2 + CO2 + H2O
moles CaCO3 = M x L = ??
Convert moles CaCO3 to moles HCl using the coefficients in the balanced equation.
now M HCl = moles HCl/L HCl.
moles CaCO3 = M x L = ??
Convert moles CaCO3 to moles HCl using the coefficients in the balanced equation.
now M HCl = moles HCl/L HCl.
