the number of moles of O2 needed to produce 14.2g of P4O10 from P?

  • Chemistry -

    How many moles of P4O10 is in 14.2 grams?

    Of that, wouldnt 10/14 of that be O, and 5/14 of that O2?

    Check my thinking.

  • Chemistry -

    there is .05 moles of P4O10 in 4.2 g, so then there will be 5/14 of O2, right? but wouldn't the ratio be 5 to 2? I'm confused :(

  • Chemistry -

    No the ratio of O2 to P is 5:4 Balance the reaction equation of P and O2 to verify.

  • Chemistry -

    so the answer would be .0625 mol of O2, right?
