the molar mass of nitrogen (n₂) is 28.02 g/mol. what is the mass, in grams, of 4.60 mol of n₂?\n0.164 grams\n6.09 grams\n23.4 grams\n129 grams
Answer
Explanation:
Step1: Recall mass - mole relationship
The formula is $m = n\times M$, where $m$ is mass, $n$ is amount in moles, and $M$ is molar mass.
Step2: Substitute given values
Given $n = 4.60\ mol$ and $M=28.02\ g/mol$, then $m=4.60\ mol\times28.02\ g/mol$.
Step3: Calculate the mass
$m = 4.60\times28.02=128.892\approx129\ g$.
Answer:
129 grams
