How many moles of phosphorus are in a 73.5 mol solution of P4O10?
There are 73.5 moles of P4O10 per kg of solution. Each P4O10 molecule weighs approximately 283.88 g. P makes up 123.88 or about 77.43% of this. 73.5 moles of P4O10 weighs about 20865.18 g. 77.43% of 20865.18g is 16155.91 g. Multiply this by the inverse of the molar mass of P (30.97g /mol) and your answer should be approximately 521.66 moles of P.
How many moles of oxygen are in one mole of calcium carbonate?
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
How many moles of oxygen are produced from 14 moles of potassium chlorate?
2KClO3 + heat -> 2KCl + 3O2 14 moles KClO3 (3 mole O2/2 mole KClO3) = 21 moles oxygen made This is a common industrial method of producing oxygen.
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 atoms of oxygen are in 0.100 moles of silicon dioxide?
There are 2 atoms of oxygen in each molecule of silicon dioxide (SiO2). Therefore, in 0.100 moles of SiO2, there would be 0.100 moles * 2 atoms = 0.200 moles of oxygen atoms. Finally, since 1 mole of any element contains 6.022 x 10^23 atoms, there are (0.200 moles) * (6.022 x 10^23 atoms/mole) = 1.204 x 10^23 atoms of oxygen in 0.100 moles of silicon dioxide.
How many moles of phosphorus atoms are there in 8 moles of P4O10?
Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus

How many grams of H3PO4 are produced when 10.0 moles of water react with an excess of P4O10?
1 mole of P4O10 reacts with 6 moles of water to produce 4 moles of H3PO4. Therefore, 10.0 moles of water will produce (10/6)*4 moles of H3PO4. To convert moles to grams, multiply the number of moles by the molar mass of H3PO4.
What number of moles of O2 is needed to produce 142 grams of P4O10 from P?
We first calculate the molar mass of P4O10, which is 284 g/mol. Then we convert the given mass of P4O10 (142 g) to moles using its molar mass. There is a 1:4 molar ratio between P4O10 and O2 in the reaction, so we multiply the moles of P4O10 by 4 to find the moles of O2 needed.
How many moles of oxygen are there in one mole of hydrogen peroxide?
In one mole of hydrogen peroxide (H2O2), there are two moles of oxygen atoms.
