What volume of hydrogen would be produced by the reaction of 2.00g of Mg with an excess of hydrochloric acid at STP. Using this equation Mg+HCl

  • Chemistry -

    Mg + 2HCl ==> MgCl2 + H2

    Convert 2.00 g Mg to moles. moles = grams/molar mass.

    Using the coefficients in the balanced equation, convert moles Mg to moles H2.

    Now convert moles H2 to volume. moles x 22.4 L/mol = ??L
