consider the following reaction: Mg(s)+ 2HCl(aq) --> MgCl2 (aq)+H2 (g)

What minimum amount of 1.75 M HCl is necessary to produce 27.5 L of H2 at STP?

  • CHEMISTRYYY -

    Convert 27.5 L H2 at STP to moles. L/22.4 = moles.

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

    M = moles/L. Convert moles HCl to L.
