This depends on the compound.
25.0 grams Na2SO4 ( only way this compound is possible ) 25.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams) = 0.176 moles Na2SO4 -----------------------------
3,42 moles of phosphorus trichloride have 469,6686 g.
This depends on the molar mass of the compound involved.
16 grams of oxygen how many moles is 0,5 moles.
The answer is 1,576 mol.
Molar mass of MgCl2 is 95gmol-1. So there are 0.566 moles in this mass.
How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
2,55 moles of the compound CO have 71,4 grams.
This depends on the compound.
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
25.0 grams Na2SO4 ( only way this compound is possible ) 25.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams) = 0.176 moles Na2SO4 -----------------------------
3,42 moles of phosphorus trichloride have 469,6686 g.
This depends on the molar mass of the compound involved.
Dinitrogen tetraoxide, or N2O4 has a molar mass of 92.011 grams per mole. This means there are 0.0435 moles present.
16 grams of oxygen how many moles is 0,5 moles.
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.
