How many moles of HClO4 are needed to react in excess P4O10 to produce 324.5 moles of Cl2O7?
The answer is 699 moles perchloric acid.
How many moles are in 100g of H2PO4?
One molecule of P2O3 = 1 mole. Go to the periodic table P = 30gm x 2 = 60 gm. O= 16 gm x 3 = 48 mg. Total is 60 + 48 = 108 gm is the weight of one molecule which is also the number of grams in 1 mole (remember 1 mol = 1 mole). So since you have 37.9 grams divide this by 108 and you have .35 moles.
Convert grams to moles?
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
Formula for moles?
number of moles = mass of the material/molar mass
What is the mass of 2.4 moles of chlorine?
The mass of 2,4 moles of chlorine is 84,08 g.
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 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 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 P4O10?
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
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 mass of phosphorus will be needed to produce 3.25 mol of P4O10?
To solve this, you need to use the mole ratio derived from the chemical formula, P4O10, and you need the molar mass of P. 3.25 mol P4O10 x 4 mol P x 30.97 g P = 403 g P .......................1 mol P4O10 1 mol P
How many mol of p are in 96 mol of p4o10?
There are 24 mol of P atoms in 96 mol of P4O10. This is because each P4O10 molecule contains 4 P atoms, so you need to divide the total moles of P4O10 by 4 to find the moles of P atoms.
How many moles of HClO4 are needed to react in excess P4O10 to produce 324.5 moles of Cl2O7?
The answer is 699 moles perchloric acid.
How many molecules of tetraphosphorus decoxide contain 29.6g of phosphorus atoms?
Since tetraphosphorus decaoxide has the formula P4O10, it contains 4 phosphorus atoms per molecule. The molar mass of P4O10 is 284.09 g/mol. To find the number of moles of phosphorus atoms in 29.6g, divide the mass by the molar mass, then multiply by Avogadro's number (6.022 x 10^23) to get the number of molecules.
How many moles are in 100g of H2PO4?
One molecule of P2O3 = 1 mole. Go to the periodic table P = 30gm x 2 = 60 gm. O= 16 gm x 3 = 48 mg. Total is 60 + 48 = 108 gm is the weight of one molecule which is also the number of grams in 1 mole (remember 1 mol = 1 mole). So since you have 37.9 grams divide this by 108 and you have .35 moles.
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How can one determine the number of moles in a substance using the formula for finding moles?
To determine the number of moles in a substance, you can use the formula: moles mass / molar mass. Simply divide the mass of the substance by its molar mass to find the number of moles.
