A sample of gas occupies 6 ml at stp. at what pressure would this sample occupy 500 ml if the temperature is changed to 525◦c? answer in units of torr.

Respuesta :

from  the  combined  gas  law
that  is P1V1/T1=P2V2/T2
P2  is  therefore T2P1V1/TIV2
A  gas  at  STP has   a temperature of  273k and  a  pressure of  760torr
 P1=760torr
T1=273K
V1=6ml
P2=?
T2=525+273=798K
V2=500ml

P2 ={(798k  x760 torr x 6ml) /(273k x500ml)} = 26.7 torr
