for each mole of anything there is 6.022x10^23 molecules. Therefore for 5 moles of water there is 5 x 6.022x10^23 = 3.011x10^24 molecules of water
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
4 moles of oxygen atoms are present in 4 moles of H2O
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
A number of atoms/molecules in a given number of moles is regardless of the substance unless it deals with stoicheometry. One mole represents a number of Avogadro's constant, approximately 6.022 x 10^23. Therefore there are 1.91 x 10^25 molecules of water in 31.8 moles.
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).

A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
To calculate the number of molecules, first convert 450 g of water to moles (8 moles). With a 1.3 m solution, there are 1.3 moles of sucrose for every 1 liter of water. So, you will need 10.4 moles of sucrose for 8 moles of water. Finally, use Avogadro's number to convert moles to molecules, giving you approximately 6.23 x 10^23 molecules of sucrose.
4 moles of oxygen atoms are present in 4 moles of H2O
One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.

3.2 moles of water (H2O)
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
For every mole of C3H8 that reacts, 4 moles of water are formed. Therefore, 5.0 moles of C3H8 will form 5.0 x 4 = 20 moles of water. To convert moles to molecules, you would then multiply by Avogadro's number (6.022 x 10^23 molecules/mol). So, 20 moles of water would equal 20 x 6.022 x 10^23 = 1.2044 x 10^25 molecules of water.
There are approximately 1.204 x 10^24 molecules in 2 moles of water. This is because 1 mole of a substance contains 6.022 x 10^23 molecules. Therefore, 2 moles would contain twice that number.
The value is 1,328.10e-3 moles.
