Question

What is the mass of amonia in 3.01×10 *
23

Answer 1

Answer:

Explanation:

No. of molecules of the Ammonia = 3.01 × 10²³

Molar Mass of the Ammonia = 17 g/mole.

Using the Formula,

No. of Molecules = Mass/Molar Mass × Avogadro's Number.

⇒ 3.01 × 10²³ = Mass/17 × 6.022 × 10²³

⇒ Mass = 17/2

∴ Mass = 8.5 g.

Hence, the Mass of the Ammonia is 8.5 g.
