Which contains more molecules, 8.69 x 1024 molecules of water or 14.55 mol of water?
To determine which contains more molecules, we need to compare the number of molecules in each quantity of water.
1 mole of water contains 6.022 x 10^23 molecules of water. Therefore, 14.55 mol of water would contain:
14.55 mol x 6.022 x 10^23 molecules/mol = 8.757 x 10^24 molecules of water
Comparing this to 8.69 x 10^24 molecules of water, we can see that 14.55 mol of water contains more molecules.
