The volume of a gas is 450 ml when its pressure is 1.00 atm. if the temperature of the gas does not change, what is the pressure when its volume is changed to 2.00 l?
use .
0.225 atm
0.444 atm
2.25 atm
4.44 atm

At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

P2 = P1 x V1 / V2

P2 = 1 x .450 / 2

P2 =.225 atm

Hope this answers the question. Have a nice day.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .
