Answer and Explanation:

252.0649 g/mol

Nitrogen: 14.007 g/mol

Hydrogen: 1.00794 g/mol

Chromium:  51.9961 g/mol

Oxygen:  15.999 g/mol

( 2 x14.007 ) +( 8 x1.00794 ) + ( 2 x 51.9961 )+(7 x15.999 )=252.06 g/mol

Answer:

346.05 g/mol

Explanation:

To find Molar Mass you basically just need to add up the atomic masses of the elements in the compound then add g/mol after.

So you would add:

(14.01+4x1.01)+(2x52.00)+(2x16.00x7)

(18.05)+(104)+(224)

=346.05 g/mol

*I hope that 0 is referring to Oxygen, if It isn't, this is not correct!*
