Question

How many moles are 21.67 L of NH4CI?

Answer 1

Answer:

0.967mole

Explanation:

Given parameters:

Volume of NH₄Cl  = 21.67L

Unknown:

Number of moles  = ?

Solution:

If we assume that the volume was taken at standard temperature and pressure,

 Then;

  Number of moles  = $\frac{volume }{22.4L}$  

 Number of moles  = $\frac{21.67}{22.4}$   = 0.967mole
