How many moles of water molecules h2o are present in a 27 rams sample of water?
Divide mass of 27 g H2O by its molar mass of 18.0 g.mol−1 H2O and you get the number of moles: 1.5 mole H2O
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of 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 molecules of water make up 5 moles?
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
Why is it acceptable to add water to the titration flask?
Once you have measured out your sample and transferred it to your flask, the absolute amount (moles) of sample is fixed. Adding water to the flask will change the concentration in the flask, titrating also adds volume to the flask as well as reacting with the sample. However, the number of molecules of sample you put into the flask will not change by simply diluting it with water.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
How many moles of water molecules h2o are present in a 27 rams sample of water?

How many moles of water are present in half mole of water?
Your question is irrelevant. I think that you were trying to find the number of molecules present in half a mole of water. 1 mole of water contains 6.023 * 1023 number of molecules. Hence half mole contains half of that number of molecules which is 3.0115*1023.
How many molecules of water make up 5 moles?
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
How many Moles of water are present in 180.00 gm of water?
9.991 Moles (water) 8.982 Moles (heavy water)
How many molecules of water is present in 10 ml of water?
Assuming a density of 1.0 g/ml for water, then 10 ml H2O = 10 g10 g H2O x 1 mol/18 g = 0.5555 moles H2O0.5555 moles x 6.02x10^23 molecules/mole = 3.34x10^23 molecules of H2O in 10 ml

A 3.677 g sample of NaC2H3O2 • 3H2O is heated in a test tube until all of the water molecules have driven off. The NaC2H3O2 remaining in the test tube has a Ma’s’s of 2.216 g. Determine the ratio moles of water to moles NaC2H3O2 in the original compound?
