PH3 has a mass of 17.33 grams, what is the mass in grams of H2 produced?

4 PH3 -> P4 + 6 H2

  • chemistry - ,

    Add up the numbers to get the molar mass of phosphine, PH3 = 33.998 g/mol
    molar mass of hydrogen, H2 = 2.0159
    4 mol of PH3 yields 6 mol H2
    Mass of Hydrogen
    = 17.33*(6*2.0159)/(4*33.998)
    = 1.541 g

    Check my calculations.
