how many moles are in 500. g mgbr2? molar mass mgbr2 = 184.11 g/mol ? mol mgbr2

Explanation:

Step1: Identify the formula

Use the formula $n=\frac{m}{M}$, where $n$ is the number of moles, $m$ is the mass, and $M$ is the molar - mass.

Step2: Substitute the values

Given $m = 500. g$ and $M=184.11\ g/mol$, then $n=\frac{500.}{184.11}$.

Step3: Calculate the result

$n\approx2.72\ mol$.

Answer:

$2.72$
