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.
What is the land mass of the Bahamas?
5400 square miles
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 many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
Formula for moles?
number of moles = mass of the material/molar mass
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?
10 moles of oxygen atoms or 5 moles of oxygen molecules.
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.
What number of moles of O2 is needed to produce 142 grams of P4O10 from P?
0.125 mole
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 is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
Is P4O10 acidic or basic?
P4O10 is acidic.
