Question

what is the molar mass of the ionic compound bacl2? bacl2 = ? $\frac{g}{mol}$

Explanation:

Step1: Identify molar - masses of elements

The molar mass of Ba is 137.33 g/mol and of Cl is 35.45 g/mol.

Step2: Calculate molar - mass of BaCl₂

The formula for BaCl₂ has 1 Ba and 2 Cl atoms. So, molar mass of BaCl₂ = molar mass of Ba+2×molar mass of Cl.
\[M = 137.33+2\times35.45\]
\[M = 137.33 + 70.9\]
\[M=208.23\] g/mol

Answer:

208.23 g/mol
