How many moles of hydrogen atoms are present in 2.31x10^24 molecules of CH4?
It is not a good idea to change screen names; it takes us longer to sort out the answers. Look under your screen name of Mark. It's done the same way.

To determine the number of moles of hydrogen atoms in 2.31x10^24 molecules of CH4, we need to first determine the number of moles of CH4 and then multiply it by the number of hydrogen atoms in one molecule of CH4.
Step 1: Determine the number of moles of CH4.
To do this, we can use Avogadro's number, which states that there are 6.022x10^23 molecules in one mole of any substance. In this case, we have 2.31x10^24 molecules of CH4, so the number of moles of CH4 can be calculated as:
Number of moles of CH4 = (Number of molecules of CH4) / (Avogadro's number)
= (2.31x10^24) / (6.022x10^23)
≈ 3.835 moles
Step 2: Multiply the number of moles of CH4 by the number of hydrogen atoms per molecule of CH4.
In one molecule of CH4, there are four hydrogen atoms. Therefore, the number of moles of hydrogen atoms can be calculated as:
Number of moles of hydrogen atoms = (Number of moles of CH4) x (Number of hydrogen atoms per molecule)
= 3.835 moles x 4
= 15.34 moles
Therefore, there are approximately 15.34 moles of hydrogen atoms present in 2.31x10^24 molecules of CH4.
