How many molecules of water will be present in half mole of water?
6.022 * 10^23 = 1 mole 3.011 * 10^23 = 1/2 a mole
How many molecules of water does a 50g sample of H2O have?
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.

Amylase is a catalyst (enzime).Amylose is the polysaccharide.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many molecules in 1 g of water?
3.345*10^23
How many H2O molecules are in the ocean?
There are approximately 1.332×10^24 water molecules in the ocean.
How many molecules are present in 17.0 moll of water?
To find this out you simply times 17 by avogadros number 17mol H2O X 6.022x10^23 molecules of anything/mol of anything mols cancel and you are left in molecules of H2O the answer is 1.024x10^25 molecules H2O
How many molecules of water are in 5.65 moles 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.
How many many molecules are present in 9.6 mol of C2H4?
There are approximately 5.8 x 10^24 molecules in 9.6 mol of C2H4. This is calculated using Avogadro's number, which is 6.022 x 10^23 molecules/mol.
