Question

What is the molecular weight (mass) for Ba(NO3)2?

275.35 g/mol
261.34 g/mol
199.33 g/mol

Answer 1

261.34
`gmol^{}`

Answer 2

261.34 g/mol

Step-by-step explanation:

The mass of barium nitrate is done by Molecular weight calculation:

First the barium=137.327 + then adding with the nitrate (14.0067 + 15.9994*3)*2← then lastly multiplying all of the two inside it
