What mass of water, in grams, would have to be decomposed to produce 28.7 L of molecular oxygen at STP?
i think you can use stoichiometry for this question. i shud helpposted by sabeen
At STP, 1 mol = 22.4L
so, convert L O2-> mol O2
then, convert mol O2-> mol H20 by mole ratio
finally, multiply by molar mass H2O
