How many moles of water molecules H2O are present in a 27 gram sample of water?
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).
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.
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
How many moles of water molecules H2O are present in a 27 gram sample of water?
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 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 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.
How much water, in the form of H2O molecules, is present in 6 moles of a substance?
6 moles of a substance contain about 3.6 x 1024 water molecules.
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 moles of water H2O contain 2.0X1022 molecules of water?
6,022140857.1023 molecules---------------------------------------------1 mole2.1022 molecules--------------------------------------------------------------x molex = 0,033 moles
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 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
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
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?
