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
