hydrogen gas is collected in a bottle, and the pressure of the gas is 892 torr at 24 °C. what is the pressure of hydrogen gas when the temperature decreases to 20 °C?

(P1/T1) = (P2/T2)


Dear Dr Bob:
is this a right answer.

892/293 = P2/297
P2= 880 torr

Please reply for me this urgent.
Thanks

    I get 879.9865 torr which rounds to 880 torr. We are allowed 3 significant figures from 892. Good work.
