Confused with math chemistry

[Calie006]

how many atoms of hydrogen are in 0.500 mol of ch3oh molecules?

I don't know how to approach the question...

Could anyone please help me?

In 1 mol of CH₃OH, you have 4 H-atoms (because 3 H-atoms are attached to the C-atom, and one H-atom in the OH group). That means in 0.500 mol of CH₃OH, you have 2 H-atoms since it is halved. And then we have Avogadro's constant: 6.02 * 10²³.

 

The question asks for how many hydrogen atoms there are in 0.500 mol CH₃OH. Using the numbers that we have (Avogadro's constant and no. of H-atoms), the answer of the question will be something like:

H-atoms in CH₃OH = 2 * 6.02 * 10²³ = ~1.2 * 10²⁴

 

I hope this helped, and that I didn't do any mistakes
