Question
There are × 1024 hydrogen atoms in 2 moles of benzene, C6H6.Give the answer to 3 significant figures (the × 1024 is not required in the answer).
Solution
Sure, I can help with that. Here are the steps:
-
First, we need to know the number of moles of hydrogen in benzene. Benzene (C6H6) has 6 hydrogen atoms. So, in 2 moles of benzene, there are 2*6 = 12 moles of hydrogen.
-
Next, we use Avogadro's number to find the number of atoms in these moles. Avogadro's number is 6.022 x 10^23, which is the number of atoms in one mole.
-
So, the number of hydrogen atoms in 12 moles is 12 * (6.022 x 10^23) = 7.226 x 10^24.
-
To three significant figures, this is 7.23 x 10^24.
