17 cl 35.45 56 ba 137.33 what is the molar mass of the ionic compound bacl2? bacl2 = ? $\frac{g}{mol}$
Answer
Explanation:
Step1: Identify molar - mass of elements
The molar mass of Ba is $137.33\ \frac{g}{mol}$ and of Cl is $35.45\ \frac{g}{mol}$.
Step2: Calculate molar - mass of $BaCl_2$
The formula for $BaCl_2$ has 1 Ba and 2 Cl atoms. So, $M = 1\times137.33+2\times35.45$. $M=137.33 + 70.9$. $M = 208.23\ \frac{g}{mol}$.
Answer:
$208.23$
