if 500 ml of HCl solution is needed to react with 2.43 g of Mg, what is the molarity of the HCl solution?

  • chemistry urgent -

    Mg + 2HCl ==> NgCl2 + H2

    mols Mg = grams/molar mass
    Convert moles Mg to moles HCl using the coefficients in the balanced equation.
    Convert moles HCl to volume using M = moles/L.
