What is the mass, in grams, of 9.13×1024 molecules of methanol (CH3OH)?

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

what are the statements

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

i think it's letter a.
