The molar mass of Aluminium sulphite Al2(SO3)3.
Explanation:
To calculate the mass of the Aluminium Sulphite Al2(SO3)3
Two aluminium atoms: 2(26.98) + (32.07 + 48.00) 3
= 53.96 + (80.07) 3
=294.17 g/mol
1 mole = 6.022*10²³ particles
The mass of the element (m) = M * n
= 294.17 * 30.5
= 8,972.18 g
Thus the mass of the element in 30.5 grms of Aluminium sulphite is 8.972g.
