An oxygen tank contains oxygen at a pressure of 70 kPa. When the pressure drops to 36 kPa, the temperature increases from 300 K to 350 K. If the initial volume is 9 L, what is the final volume? --------------- 20.4 L 84.0 L 233 L 336 L
again you begin with: pv=nrt n=n n=pV/RT p1V1/RT1=p2V2/RT2 p1V1/T1=p2V2/T2 p1V1T2=p2V2T1 V2 = p1V1T2/p2T1
@Austin_Cochran HELP!
you just need to put the numbers in equation i gave you and you get that volume is: 20.4 L
oh! thank you , you're just too smart for me
