Well 1 mole of water is 2 moles of hydrogen + 1 mole of oxygen - that is; 1.008 x 2, + 16, which is 18.016 grams. Multiply that by the number of moles - 5, so that's 90.08 grams, or about 90mL. There are 90 grams in 5 moles of water.

We assume you are converting between moles FeSO4 and gram. You can view more details on each measurement unit: molecular weight of FeSO4 or grams This compound is also known as Iron Sulfate or Ferrous Sulfate. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles FeSO4, or 151.9076 grams.

So then we will have 63.52g of iron and 36.48g of sulphur. So the empirical formula of the compound is FeS.

The reason why analysis shows that FeO has a non - stoichiometric composition with formula Fe0. 950 is that : The non - stoichiometry reflects the ease of oxidation of Fe^²⁺ to Fe^³⁺ effectively replacing a small portion of Fe^²⁺ with two thirds their number of Fe^³⁺ . 3Fe^²⁺ = 2Fe^³⁺ to maintain electrical neutrality.

How Many Molecules are contained in 0.25 moles of Fe? 1 mol contains 6.02 x 10^23 molecules. So 0.25 mols will contain 0.25 x 6.02 x 10^23 molecules.
755031
Well, one mole is equal to Avogadro's Number, or 6.02210 x 10^23 particles. Since you are not talking about the amount of oxygen atoms in 3 moles of O2, no extra multiplication is needed to compensate for that. 3 moles x (6.02210 x 10^23) O2 molecules per mole = 1.80663 x 10^24 O2 molecules.
