As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction. Notice that the reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.

The molecular masses of hydrogen, oxygen and water are 2 g/mole, 32 g/mole and 18 g/mole respectively. 2×2=4 g of hydrogen reacts with 1×32=32 g of oxygen to form 2×18=36 g of water.

( 1/4 of a mole) x (6.02 x 1023 atoms/mole) = approximately 1.5 x 1023 atoms. If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

Once we do that, we get rid of the grams of water. We find moles of water. All you have to do is just divide 75 by 18 and you'll get 4.17 moles of H2O.

You have 3.14 moles of water. For each mole of water, there are two moles of 'H' and one mole of 'O'. So there will be 2 X 3.14 moles of 'H' or 6.28 moles of hydrogen atoms, remembering that a hydrogen atom is simply 'H'.

A lot. 9.34g divided by 18g/mol (the molar mass of water) gets you about 0.52 moles, times Avogadro's number of 6.02x1023 = 3.13x1023 molecules.

Each mole of ethane undergo complete combustion with 3.5 moles of oxygen and produce 3 mole of water. Hence to produce 9 mole of water by combustion of 6 moles of ethane there's requirement of 10.5 mole of oxygen.

So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅6.022⋅1023molec.

Divide the mass of water by the molar mass of water to get moles of water. 2.60 g H2 O / (18.00 g/mol H2 O) = 0.144 moles H2 O. Divide the mass of anhydrate by the molar mass of anhydrate to get moles of anhydrate.

You would get 19.969 moles. (Notice how when you simplify the units, you will end up with just moles which is the right unit.)
