Answer 1

Answer:

The Equivalent Mass of AlH3 is 30.

Explanation:

Molar Mass of one atom of Al = 27 g. [approx.]

Molas Mass of one atom of H = 1 g. [approx.]

In AlH3,

There is 1 atom of Al and 3 atoms of H.

.: Equivalent Mass of AlH3=

no. of atoms of Al × Molar Mass of one atom of Al+no. of atoms of H × Molar Mass of one atom of H =1 × 27 + 3 × 1

= 27 + 3

= 30 g.
