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

What is the most important type of intermolecular forces between molecules in a sample of pure water?
Hydrogen bonding
What is the ratio of hydrogen to oxygen in this sample of four water molecules?
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.
What does the formula indicate about the composition of a 1.0 gram sample of hydrogen sulfide?
All of the molecules are identical combinations of two hydrogen atoms and one sulfur atom.
Flask A contains 2 liters of ch4 g and flask B contains 2 liters of o2 g each gas sample has the same?
number of molecules
Do molecules have neutrons?
All stable molecules except hydrogen contain neutrons (and even hydrogen molecules contain some neutrons if you choose a large enough sample, just not many).The neutrons are found inside the atoms that make up the molecule; only hydrogen-1 (the form of hydrogen that has a nucleus consisting of a single proton) has no neutrons. Any other atom with no neutrons is radioactive and highly unstable (in the sense of "undergoes radioactive decay in fractions of a nanosecond"). On Earth, about one in one million hydrogen atoms is hydrogen-2, which has both a proton and a neutron, and is not radioactive, so around one in 500,000 hydrogen molecules contains a neutron.
At a certain temperature and pressure 0.02 mol of carbon dioxide has a volume of 3.1 L A 3.1 L sample of hydrogen at the same temperature and pressure?
contains the same number of molecules
How many molecules are present in the C3H4 sample?
1.51 x 10 ^23 molecules
How many moles of N2O molecules are present in a sample that contains 5.23 moles of nitrogen atoms?
1 mole=6.02*1023 molecules or atoms5.23 moles=6.02*1023 * 5.23= {[(3.14846*1024molecules)]}
How hydrogen detected in the carbon and hydrogen test?
To test for hydrogen in the given substance, a dry sample is needed. Burn it in excess of oxygen. If the vapour turns white copper sulfate into blue colour, it indicates that there is water in present in the vapour. Hence, the organic compound contains hydrogen.
If you have a water sample that contains either nitrate chloride or sulfate ions how do you determine which is present?
if you have a water sample that contains either nitrate chloride.
A sample of nitric acid contains 50 HNO3 molecules How many oxygen atoms are in this sample?
150 (50 x 3)

What is the ratio of hydrogen to oxygen in this sample of four water molecules?
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.
How many molecules are in a 2 mole sample of hydrogen?
1 mole of H2 has 6.023 x 1023 molecules So, 2 moles will have 12.046 x 1023 molecules
What does the formula indicate about the composition of a 1.0 gram sample of hydrogen sulfide?
All of the molecules are identical combinations of two hydrogen atoms and one sulfur atom.
How can you get the molar mass of insulin knowing just the grams of insulin in a sample and the number of molecules that that sample contains?
by weighing out the bit of insulin that you want to find how much of it there is
If a sample of radioactive materiel contains 17 daughter nuclide what percent of parent nuclide is present in the sample?
if all the daughters have the same parents the logical answer is 2 parents making it appproximately 11.765% Or if the parents were not present in the sample O%
