half liter of air under 360mm pressure is compressed to 200ml.Taking t

1.	half liter of air under 360mm pressure is compressed to 200ml.Taking the temperature to remain constant.find the new pressure
Answer» Answer: Ideal GAS equation is given by pV=nRT ...(i) For OXYGEN, p=1atm,V=1L,n=n0 Therefore equation (i) becomes ∴1×1=no2RT ⇒no2=RT1 For NITROGEN p=0.5atm,V=2L,n=nN ∴0.5×2=nN2RT ⇒nN2=RT1 For mixture of gas pmixVmix=nmixRT Here, nmix=nO+nN2 ∴RTpmixVmix=RT1+RT1 ⇒p

Answer»

Answer:

Ideal GAS equation is given by

pV=nRT ...(i)

For OXYGEN, p=1atm,V=1L,n=n0

Therefore equation (i) becomes

∴1×1=no2RT

⇒no2=RT1

For NITROGEN p=0.5atm,V=2L,n=nN

∴0.5×2=nN2RT

⇒nN2=RT1

For mixture of gas

pmixVmix=nmixRT

Here, nmix=nO+nN2

∴RTpmixVmix=RT1+RT1

⇒p
