calculate the number of moles in the following molecules
1)1.2046x10^24molecules of oxygen
2)9.000345x10^23 molecules of ammonia
3)3.024x10^24 of sulphuric 6 acid
1) To calculate the number of moles in 1.2046x10^24 molecules of oxygen, we need to convert the molecules to moles using Avogadro's number (6.02x10^23).
1.2046x10^24 oxygen molecules ÷ 6.02x10^23 molecules/mol = 2 moles of oxygen
Therefore, there are 2 moles of oxygen in 1.2046x10^24 molecules.
2) To calculate the number of moles in 9.000345x10^23 molecules of ammonia, we need to convert the molecules to moles using Avogadro's number (6.02x10^23).
9.000345x10^23 ammonia molecules ÷ 6.02x10^23 molecules/mol = 1.5 moles of ammonia
Therefore, there are 1.5 moles of ammonia in 9.000345x10^23 molecules.
3) To calculate the number of moles in 3.024x10^24 molecules of sulfuric acid, we need to first determine the molecular formula for sulfuric acid, which is H2SO4. This means there are 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms per molecule.
Next, we need to convert the number of molecules to moles using Avogadro's number.
3.024x10^24 sulfuric acid molecules ÷ 6.02x10^23 molecules/mol = 5.03 moles of sulfuric acid
Therefore, there are 5.03 moles of sulfuric acid in 3.024x10^24 molecules.
