How many grams of P2O5 will be produced from 125 g of P?
From every two atoms of P, one molecule of P2O5 is formed. The relative formula mass of two atoms of P (phosphorous) is 62, whereas for one molecule of P2O5 it is 142. The mass of P2O5 formed is therefore 142/62 times the mass of P we started with. This comes out to 286.3g (to one decimal place).
How many moles of phosphorus are needed to form 8.6 mol p2o5?
Molar mass of P2O5 is 142gmol-1. You need 17.2 moles of p.
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 atoms are contained in 97 grams of platinum?
It's 97g/195.1g Pt = .497 .497 x 6.022x10^23= 2.993 mols/atom.

How many atoms are in 740 g of P2O5?
740 grams P2O5 (1 mole P2O5/141.94 grams)(6.022 X 10^23/1 mole P2O5) = 3.14 X 10^24 atoms of P2O5

How many total atoms are in 0.750 of p2o5?
Assuming 0.75 g of P2O5,moles of P2O5 = 0.0053 moles1 molecule of P2O5 has 7 atoms.so reqd. no. is 2.23 X 1022.
How many molecules are in P2O5?
The formula P2O5, could itself represent one molecule of diphosphorus pentoxide. Or you could specify any number of moles. One mole of P2O5 would be 6.022 x 1023 molecules of P2O5. Two moles would be 1.204 x 1024 molecules, and so on.
How many grams are in technetium?
The atom doesn't contain gram which is a unit of mass.
How many moles of phosphorus are needed to form 8.6 mol p2o5?
Molar mass of P2O5 is 142gmol-1. You need 17.2 moles of p.
How many moles are in the element uranium?
1 atom-gram of uranium = 238,02891 grams
What is the weight of an atom in grams?
1.66 × 10^-24 grams per nucleon. So you need to know what element you are interested in, then look at the atomic mass number to find out how many nucleons (protons + neutrons) are in the atom, and multiply by 1.66 x 10^-24
How do you determine how many grams are in atoms?
an atom weighs about 1o trillionths of a trillionth of a trillionth of a gram that is all I know.
