A closed gas system at 855K has a colume of 6060mL and pressure of 935 mmHg. If the temp. is increased to 950.0 celcius , the volume decreases to 3910mL. What is the resulting pressure? Express answer in kPa. Is 202,000,000kPa right?

In approximate terms, the temperature remains constant, but volume decreases by 1/3...so P should go up by 1/3. Your answer is far, far from that.
P2= T2*P1*V1/T1=(950+273)*935*6060/((3910*(855+273) )
Then, convert the pressure (above in mmhg) by multiplying by 101.3kpa/760mmhg
