Mg reacts with 150 mL of 6.00M Hcl through single replacement to produce hydrogen gas. How many liters of hydrogen gas are produced? (tell me how you got it please)

  • Chem -

    I assume this is for STP.
    Write and balance the equation.
    Mg + 2HCl ==> H2 + MgCl2

    How many moles HCl did you use? M x L = moles.
    Using the coefficients in the balanced equation, convert moles HCl to moles H2.
    Now convert moles H2 to liters knowing that 1 mole H2 gas occupies 22.4 L at STP.
    Post your work if you get stuck.
