a chemist has 2.0 mol of methanol (ch₃oh). the molar mass of methanol is 32.0 g/mol. what is the mass, in grams, of the sample? 16 grams 30 grams 32 grams 64 grams
Answer
Explanation:
Step1: Recall mass - mole formula
$m = n\times M$ where $m$ is mass, $n$ is number of moles and $M$ is molar mass.
Step2: Substitute given values
$n = 2.0\ mol$ and $M=32.0\ g/mol$, so $m=2.0\ mol\times32.0\ g/mol$.
Step3: Calculate the mass
$m = 64\ g$
Answer:
64 grams
