The name would be aluminum nitrate. and the molar mass would be 213 because aluminum AMU (atomic mass unit) is 27 (26.98) plus NO3's AMU is 62 (62.004) and because there is 3 NO3's that is 186. 186 plus 27 is 213

Answer:

The name is aluminium nitrate and the molar mass is 213 grams per mole

Step-by-step explanation:

You have to considerer the atomic mass unit of each elements first

Al= 27 amu

N= 14 amu

O= 16 amu

Then you need to count every atom:

Al=1

N=3

O= 9

Finally, multiply by its atomic mass unit

Al= 1*27=27

N=3*14=42

O= 9*16=144

Add

213
