One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.

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.
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 in 2.0 moles of Fe(NO3)2?
The number of molecules is 12,044280.10e23.
How many moles of H are in 2.95 moles of water?
In water (H2O), there are 2 moles of hydrogen (H) atoms for every 1 mole of water. Therefore, in 2.95 moles of water, there are 2 * 2.95 = 5.9 moles of hydrogen atoms.
How many molecules are present in 3 moles of methanal?
The reaction is :- 2C2H6 + 7O2 ----------> 4CO2 + 6H2O When one mole ethane is combusted 7/2 moles of oxygen are used. When 3 moles of ethane are combusted 3 x 7/2 moles of oxygen used. No. of oxygen molecules consumed =6.022 x 1023 x7/2= 21.077 x 1023=2.107 x 1024 molecules.

How many moles of Hydrogen are in 2 moles of H2O?
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
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 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 of oxygen gas are needed to make 4 moles of water?
Two moles of oxygen gas are needed to make 4 moles of water in the reaction: 2H2 + O2 -> 2H2O.
How many molecules are in 2.0 moles of Fe(NO3)2?
The number of molecules is 12,044280.10e23.
If you have 2 tons of water how many moles of water do you have?
yes
How many moles of H are in 2.95 moles of water?
In water (H2O), there are 2 moles of hydrogen (H) atoms for every 1 mole of water. Therefore, in 2.95 moles of water, there are 2 * 2.95 = 5.9 moles of hydrogen atoms.

What quantity of Oxygen contains same number of molecules as 36 grams of water?
36 grams of water is equal to 2 moles. Therefore, to find the quantity of oxygen molecules that contain the same number of molecules as 36 grams of water, you would need 4 moles of oxygen since the molecular formula of water is H2O.
calculate the number of moles in H2 molecules in 4g H2?
2 moles.
What does the 2 in 2NH3 mean?
The coefficient (in this case a 2) indicates the number of moles or molecules of the compound. So, 2NH3 means there are 2 moles or 2 molecules of ammonia (NH3).
