4 P + 5 O2 ==> P4O10

If you have 24.98 grams of P and 74.99 grams of O2, how many moles of each compound do you have present?

• chemistry -

Take the weight of each and divide them by their respective molecular weights.

e.g.

24.98 g of P *(1 mole of P/31.0g of P)= moles of P

I'll let you do the other one.
