Answer:

342.14g/mol.

Explanation:

The molar mass of Al2 (SO4)3 is 342.15g/mole.

Reasons that one aluminum atom=26.98. Therefore two aluminum atoms:=2(26.98 g/mole) =53.96 g/mole.

Mass of SO4=96.06g/mol.

Therefore molar mass of Al2(SO4)3= 53.96+(96.06)×3=342.14g/mol

Answer:

342.17 g/mol

Explanation:

Al= 26.98    

S= 32.07

O= 16.00

To calculate that you would have

2(26.98) since there are two Als

and then you have to distribute the 3 to the S and O so...

3S and 12O

which is

3(32.07) + 12(16.00)

which means you add

2(26.98) + 3(32.07) + 12(16.00)

=53.96 + 96.21 + 192

=342.17

there you Go! the final answer is 342.17 g/mol.
