Answer 2

Mass of 4 moles of NH3 equals to 68g

Given: 4 moles of NH3

To Find: Mass of given moles of NH3

Solution:

We know that,

Number of moles= Mass / Molecular mass

Molecular mass of NH3 = 14 + 3 × 1 = 17

Number of moles are 4 as per question

So, 4 = Mass / 17

Mass = 68g.

Therefore, Mass of 4 moles of NH3 equals to 68g.
