#5 5. A 21.5 L sample of gas is at 725 mmHg and 25°C. If the volume changes to 24.9 L and the pressure changes to 755 mmHg, what will be the new temperature?6. A 348 mL sample of gas is at 675 torr and 13°C. If the pressure changes to 582 torr and the temperature changes to 11°C, what will be the new volume?

Given that,V1 = 21.5 L atm P1 = 725 mm Hg = 725/760 = 0.9539 atm1 atm = 760 mm HgT1 = 25oC = 25+273.15 = 298.15 KV2 = 24.9 LP2 = 755 mm Hg = 755/760 = 0.9934 atmT2 = __ K PVT = constant P1V1T1 = P2V2T2 Use the above formula to determine T2 P2V2T1P1V1 = T2T2 = 0.9934 atm x 24.9 L x 298.15 K0.9539 atm x 21.5 L = 359.5977 K ~ 359.6 K (rounded off to 2 sig fig)T = 359.6 - 273.15 = 86.45oCTherefore the new temperature will be 86.45oC
