How many moles of P2 O5 are produced from 8.00 mole of O2?
Balanced equation first. 4P + 5O2 -> 2P2O5 8.00 mole O2 (2 mole P2O5/5 mole O2) = 3.20 moles P2O5 produced
How many moles O2 must react with excess H2 to form 7.89 mol H2O?
Oxygen limits the reaction, so......Balanced equation. 2H2 + O2 -> 2H2O 7.89 mole H2O (1 mole O2/2 mole H2O) = 3.95 mole oxygen gas needed ------------------------------------------
How many moles of H2O are product from reaction of 355 g of O2?
Balanced equation. 2H2 + O2 -> 2H2O 355 grams O2/32 grams = 11.1 moles O2 check for limiting reactant 11.1 moles O2 (2 mole H2/1 mole O2) = 22.2 mole H2 and H2 has no where near that many moles, so limits and drives reaction so, as they are one to one...... 22.2 moles of H2O are produced
How many atoms of O2 are in a 1.76sample of CO2?
1.76 grams CO2 (1 mole CO2/44.01 grams)(2 mole O/1 mole CO2)(6.022 X 10^23/1 mole O2) = 4.82 X 10^22 atoms of oxygen gas
How many moles of cesium chlorate must be decomposed to produce 2.7 moles of oxygen gas?
2CsClO4 -> 2Cs + Cl2 + 4O2 2.7 moles O2 (2 moles CsClO4/4 mole O2) = 1.4 mole CsClO4 needed
How many moles of P2 O5 are produced from 8.00 mole of O2?
Balanced equation first. 4P + 5O2 -> 2P2O5 8.00 mole O2 (2 mole P2O5/5 mole O2) = 3.20 moles P2O5 produced
How many particles are there in a mole of O2?
6.02214076×1023

How many moles of oxygen gas O2 needed to react with 4.00 mol of Mg?
Do you mean this reaction? 2Mg + O2 -> 2MgO 4.11 moles Mg (1 mole O2/2 mole Mg) = 2.06 moles oxygen gas consumed --------------------------------------------------
How many hydrogen atoms are in Na2HPO4?
1 atom per mole
How many moles of oxygen are needed to react completely with 2.3 moles of H2S 2H2S plus 3O2 2SO2 plus 2H2O?
H2S (g) + 2 O2 (g) --> H2SO4 (l) 1 mole + 2 mole --> 1 mole You will need 2 moles of O2
For the reaction 2 S 3 O2 --- 2 SO3 how much SO3 can be produced from 8.0 g O2 and excess S in mols?
2S + 3O2 >> 2SO3 8.0 grams O2 (1 mole O2/32 grams)(2 mole SO3/3 mole O2) = 0.1666 ( 0.17 moles SO3 ) and also, 0.1666 moles SO3 (80.07 grams/1 mole SO3) = 13.34 ( 13 grams SO3 ) if needed.
How many moles and how many molecules are in 64 g of oxygen gas?
1 mole O2 weighs 32 gso 64 g O2 is 2 mol O2 gaswhich has 2 X 6.022 X 1023 = 1.2066 X 1024 molecules of O2
Calculate the number of moles of oxygen atom in 18.1 mole of CH2O?
Since there is only 1 oxygen atom in CH2O, there is the same amount of oxygen atoms as there are molecules of CH2O. So the answer is 18.1 mole. But if you burn it, you will form oxygen in its natural form, which is O2. So there will only be the half the amount of the oxygen. Then the answer would be 18.1 / 2 = 9.05 mole.
How many moles of the product form when 0.016 mol of O2 completely reacts 2Ca plus O2 ----- 2CaO?
.183mol CaO Ca is your limiting reactant, O2 is your excess reactant. thus 7.34g Ca = .183mol Ca, since the balanced reaction is 2Ca + 1 O2 -> 2 CaO, 1 mol Ca = 1 mol Cao and .183mol CaO is produced.
