    Can anyone help me solve this please? Thank you!

    1. A solution of hydrochloric acid of volume 25.0 cm3 was pipetted onto a piece of marble which is calcium carbonate. When all action had ceased, 1.30g of the marble had dissolved. Find the concentration of the acid.

    Equation: CaCO3 + 2HCl -> CaCl2 + CO2 + H2O

    You need to find the molecular mass of calcium carbonate and how many moles of it is in 1.3g.
