the molar mass of barium, ba, is 137.33 g/mol. how many grams of barium are in 2.64 mol ba? ? g ba

Explanation:

Step1: Recall the mass - mole relationship

The formula is $m = n\times M$, where $m$ is mass, $n$ is the amount of substance in moles, and $M$ is the molar mass.

Step2: Substitute the given values

We know that $n = 2.64\ mol$ and $M=137.33\ g/mol$. So $m=2.64\ mol\times137.33\ g/mol$.

Step3: Calculate the mass

$m = 2.64\times137.33=362.5512\ g$.

Answer:

$362.55\ g$
