IF 0.5 MOL NITROGEN GAS HAS A VOLUME OF II.0 L SOME TEMPERATURE AND

Chemistry
1 answer:
DENIUS [597]3 years ago
8 0

Answer:

17.92L or 17.92dm³1

Explanation:

number of moles of a gas = volume of that gas/ 22.4(S.V.P)

0.8 mol = x / 22.4

cross multiplication

x = 22.4 × 0.8

x = 17.92

:. the volume of 0.8 mol of nitrogen gas is 17.92dm³ or 17.92L

What will be the new volume of a 250 mL sample of gas at 300 K and 1 atm if heated to 350 K at 1 atm?
AlekseyPX

The   new volume of a 250  Ml   sample of gas at 300k  and  1atm  if  heated to 350 k  at  1 atm  is  291.67  Ml



<u>calculation</u>

This  is  solved  using  the  Charles  law formula  since the  pressure  is constant.

that is V1/T1 = V2/T2  where,

V1 =250 ml

T1=300  K

V2=?

T2= 350 k


by making V2 the subject   of  the formula  by  multiplying  both side by T2

V2= T2V1/T1

V2= (350 K x 250 ml) / 300K =291.67 Ml
