Question

What is the molar mass of barium chloride, `BaCl_2`?

Answer 1

The molar mass of `BaCl_2` is `208.233 (g)/(mol)`

Explanation:

Add the atomic mass of `Ba` with the one of `Cl_2`

`Ba=>137.327 (g)/(mol)` and `Cl_2=>2xx35.453= 70.906(g)/(mol)`

Check your periodic table if you want to see these values. It's written down.

So, the molar mass of `BaCl_2` is `137.327 (g)/(mol) + 70.906(g)/(mol)=208.233 (g)/(mol)`

Hope this helps :)
