given 83.2 g of babr2, determine the number of moles of babr2.\n1 mol babr2 = 297.13 g babr2\n? mol babr2 = 83.2 g babr2\nround your answer to two decimal places.

Answer

Explanation:

Step1: Recall mole - mass formula

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

Step2: Identify given values

We are given $m = 83.2\ g$ (mass of $BaBr_2$) and $M=297.13\ g/mol$ (molar mass of $BaBr_2$).

Step3: Calculate number of moles

$n=\frac{83.2}{297.13}\approx 0.28\ mol$

Answer:

$0.28$
