Answer 2

Answer:

190mm gh

Explanation:

GIVE N- A sample of nitrogen gas occupies a volume of 2.00 L at 756 mm Hg and 0.00° C.

The volume increases by 2.00 L and the temperature decreases to 137 K.

TO FIND - the final pressure exerted on the gas

SOLUTION -

P1= 756mm. V1= 2.00L

P2= ? V2= 4.00L

T1= 0.0C+273= 273K

T2= 173K

P1V1/T1= P2V2/T2

P2= P1 V1/ T1 ×T1/V2

P2= 756mm × 2.00L × 137k/273k × 4.00L

= 190mm gh

FINAL ANSWER - 190mm gh
