Answer:

Surely you can use the interwebz….?

Explanation:

I gets #"formula mass of aluminum nitrate"-=213*g*mol^-1#.

But how did I get that mass? I looked at the Periodic Table in front of me, which tells me that molar masses of #Al#, #N#, and #O# are #27.0*g*mol^-1#, #14.01*g*mol^-1#, #16.0*g*mol^-1# respectively...and I added these together appropriately...

#{27.0+3xx14.01+9xx16}*g*mol^-1-=??*g*mol^-1#

Answer:

Molar mass: 213.01

Explanation:

Molar mass of a compound can be found by finding a periodic table and looking at the atomic mass of each element that is in the compound

Aluminium - 26.98
Nitrogen - 14.01
Oxygen - 16

#Al(NO_3)_3 = 26.98+3times(14.01+16times3) = 213.01#
