Question

What is the molar mass of barium nitrate?

Answer 1

I would say 261.337 g/mol

Answer 2

261.3404 u

Step-by-step explanation:

The symbol for barium nitrate is

Ba (NO3)2

Therefore there is

1 barium atom

2 nitrogen atoms

6 oxygen atoms

Add the molar mass of these atoms together to get the molar mass of barium nitrate

137.327 +(14.0067×2) +(16 ×6)

=261.3404 u
