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 are there in 31.8 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.


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 are there in 2 moles 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.


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 molecules of water are produced if 2.0g of sodium sulfate are produced in the above reactionH2SO4+2NaOH=H2O+Na2SO4?

The reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.


How many moles are in 3.612 X 1024 molecules of H2O?

To find the number of moles in 3.612 × 10^24 molecules of H2O, divide the number of molecules by Avogadro's number, which is approximately 6.022 × 10^23 molecules/mol. 3.612 × 10^24 molecules / 6.022 × 10^23 molecules/mol ≈ 6 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.

Which one has more molecules 9 g of water or 9 g of suger (C12 H22 O11)?

To determine which substance has more molecules, we need to calculate the number of moles for each substance using their respective molar masses. The molar mass of water (H2O) is approximately 18 g/mol, while the molar mass of sugar (C12H22O11) is about 342 g/mol. For 9 g of water, the number of moles is 9 g / 18 g/mol = 0.5 moles. For 9 g of sugar, the number of moles is 9 g / 342 g/mol ≈ 0.026 moles. Therefore, 9 g of water has more molecules because it contains 0.5 moles, which is significantly higher than the 0.026 moles in 9 g of sugar.


How many moles of water molecules h2o are present in a 27 rams sample of water?

To find the number of moles of water molecules in a 27 gram sample, you need to divide the mass by the molar mass of water (18.015 g/mol). 27 g / 18.015 g/mol = approximately 1.5 moles of water molecules.
