How much Na is needed to react with H2O to
liberate 179 mL H2 gas at STP?
Answer in units of g

Please help me with what formulas to use and what to do.

  • Chemistry -

    Write and balance the equation.
    Convert 179 mL H2 gas @ STP to mols remembering that 1 mol of a gas occupies 22,400 mL at STP.
    Using the coefficients in the balanced equation, convert mols H2 to mols Na. Then convert mols Na to grams. g = mols x atomic mass.
