Answer 2

Given:-

• Name of Compund = $\rm{Zncl_{2}}$

• Number of mole = 5.5

To Find :-

• No. of molecule in 5.5mole of in given Compund.

Formulae used:-

• No. of molecule = Mole × Avagardo Constant

☯ Now,

• → No. of mole = 5.5

• → Avagardo Constant = 6.022 × 10²³

• → No. of molecule = 5.5 × 6.022 × 10²³

• → No. of molecule = 33.121 × 10²³

Hence, The 5.5 mole of $\rm{Zncl_{2}}$ Contains 33.121 × 10²³ no. of molecule.
