How many liters of hydrogen at STP are needed to produce 0.24 mol H2O?

  • chemistry -

    You need t find the arrow key on your computer and use it. ==> or -->. Convert mols H2O to mols H2 using the coefficients in the balanced equation.
    0.24 mol H2O x (2 mol H2/2 mol H2O) = 0.24 x 2/2 = 0.24 mols H2 neded.
    volume = 0.24 mols H2 x (22.4 L/mol) = ?
