☀️

For this question –

Molar formula will be =

Now, let's find out value of n. Where–

Empirical Mass of –

Now, we are given, mass of compound is 90.07 g/mol.

Molar formula will be –

Henceforth, Molar formula will be

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
