How many milliliters of 0.200M HCl can react with 3.25g CaCO3?

  • Chemistry - ,

    balance the equation:
    2HCl + CaCO3 >> CO2 + H2O + CaCl2

    figure the moles of calcium carbonate:
    3.25/molmassCaCO3

    then you must need twice that of acid.

    2*3.25/molmassCaCO3 = volume*.2M

    solvefor volume in liters. change to milliliters.
