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?\n16 grams\n30 grams\n32 grams\n64 grams
Answer
Answer:
D. 64 grams
Explanation:
Step1: Recall mass - mole formula
$m = n\times M$ (where $m$ is mass, $n$ is amount in moles, $M$ is molar mass)
Step2: Substitute given values
$n = 2.0\ mol$, $M=32.0\ g/mol$ $m=2.0\ mol\times32.0\ g/mol = 64\ g$
