Answer:

0.908 atm

Step-by-step explanation:

At standard temperature and pressure, the temperature of 0 Celsius and pressure which is equal to the atmosphere, 1 atm.

= 0 Celsius

= 1 atm

Change in temperature causes a change in the pressure:

=248K

=?

Calculating the pressure, using Gay-Lusaac's law:

Convert the temperatures from Celsius to Kelvin:

=0 Celsius+273=273K

=248K

To find :

= = 0.908 atm
