Answer

Answer:

D. 8.08 grams

Explanation:

Step1: Recall the mass - mole relationship formula

$m = n\times M$ (where $m$ is mass, $n$ is amount in moles, $M$ is molar mass)

Step2: Identify given values

$n = 4.00\ mol$, $M=2.02\ g/mol$

Step3: Calculate the mass

$m=4.00\ mol\times2.02\ g/mol = 8.08\ g$
