Hello, I really don't understand how to solve this question. Please help! For the reaction P4O10(s) + 6H2O(l)  4H3PO4(aq), what mass of P4O10 must be consumed if 3.71  10^23 molecules of H2O are also consumed?

    3.71*10^23 molecules of H2O can be converted to moles of H2O by dividing by Avogadro's number, 6.022*10^23 for every 6 moles of H2O consumed, 1 mole of P4O10 gets consumed, so divide the number of moles of H2O by 6 to find out the number of moles of P4O10 consumed then multiply your result by the molar mass of P4O10 to figure out how many grams are being used
