Title: If the initial pressure of a system was 1.00 atm and the volume was halved and t Post by: jessyyymessyyy on Nov 12, 2014 If the initial pressure of a system was 1.00 atm and the volume was halved and the temperature was tripled, what is the final pressure?

The number of moles of gas remained the same, so n and R are constant. So the new equation would be P(1/2)V=nR(3)T To make the equation balance out, pressure needs to be 6 times the original, so the coefficient on both sides would be 3. Thus, the final pressure would be 6 atm |
