Question

The volume of chlorine gas at 400 mmHg is decreased to 200 mL at constant temperature. What is the new gas pressure?

Answer 1

a) 800 mm Hg
b) 650 mm Hg
c) 600 mm Hg
d) 400 mm Hg

Answer 2

PV = nRT

so, P1V1=P2V2 (since n, R and T are constants)


now apply, enjoy and then "eat rainbows' !! :D

Answer 3

@apoorvk My chemistry is a bit rusty, so I'm curious to know - how would you go about solving this problem since it appears V1 is not given? Unless I am mistaken.

Answer 4

Aaha. no. your chem is not rusty, this problem has missing data. you need initial data. didnt't notice that earlier.

Answer 5

Ah I see. Thanks!
