6 moles
There are 0.13 moles in 20 grams of magnesium nitrate.
The solubility of poassium nitrate in water at 20 oC is 616 g/L.
The answer is 1,83 moles.

20 moles of Al will react with water to form 60 moles of H2 and 30 moles of O2, because of the stoichiometry 2:1 in getting H2 en O2 from water, and Al needing an oxidationstate of 3+, so 1 mole is oxidized by 3 moles of H2O.

20 moles of NaOH needed to neutralize 20 moles of nitric acid
40 moles of LiOH
Molarity = moles of solute/Liters of solution Or, for our purposes, Moles of solute = Liters of solution * Molarity Moles Na2CO3 = 10.0 Liters * 2.0 M = 20 moles Na2CO3 --------------------------

4 C3H8 + 20 O2 ---> 12 CO2 + 16 H2O So 20 mol of O2 are needed.
Quinine is a drug with chemical formula C20H24N2O2. In each molecule of quinine there are 20 carbon atoms. Thus in 4.0 moles of quinine, there would be 80 moles of carbon.
20 moles of elemental sodium and 10 moles of elemental chlorine, which contains two atoms per molecule.
The chemical formula for potassium nitrate is KNO3, which means that one molecule contains five atoms. Therefore, four molecules of potassium nitrate would contain 20 atoms.
