Question

What is the molar mass of Al2(SO4)3​

Answer 1

Answer:

The molar mass of $Al_2(SO_4)_3$​ is 342.145 g/mol

Explanation:

The molar mass  is stated as the “mass per unit amount of substance”of a given chemical compound  

$Al_2(SO_4)_3$​  is Aluminium sulphate. They easily dissolve in water. It is primarily  used as a 'coagulating agent' in the drinking water purification and also in waste and sewage water treatment plants,  

We know,

Atomic weight of Aluminium =  26.981

Atomic weight of Sulphur= 32.065

Atomic weight of  Oxygen =  15.9994

Now molar mass of  $Al_2(SO_4)_3$​ (Aluminium sulphate) is

=>2(26.981)+3(32.065+4(15.999))

=>53.962 +3(32.065+63.996)

=>53.962+3(96.061)

=>53.962+288.183

=>342.145
