Question

Vapour density of ammonia is 8.5, then 85 g of
NH, at NTP will occupy.
(1) 22.4L
(2) 112 L
(3) 224 L
(4) 1120 L​

Answer 1

Answer:

vapour density of ammonia is 8.5

so molecular mass of ammonia =2*vapour density

mol. mass=2*8.5=17

number of moles of ammonia=85/17=5

according to NTP one mole =22.4l

5 mole=22.4*5l

85 g of NH3 will occupy = 112l
