V1 x P1 x T2 = V2 x P2 x T1
1. P2 = V1 x P1 x T2 / V2 x T1
760 torr ---- 1 atm
980 torr ---- x
X= 1.28 atm
V1 = 550 mL / 1000 = 0.550 L
V2 = 0.81 /1000 = 0.00081 L
T = 27 + 273 = 300 K
P2 = 0.550 L x 1.28 atm x 330 K / 0.81 L x 300 K
P2 = 1.12 atm.2. T2 = V2 x T1 x P2/ V1 x P1
P2 760 torr ---- 1 atm
1400 torr ---- x
X= 1.84 atm
V2 = 786 /1000 = 0.786 L
T1 = 18 ºF
ºC = (ºF -32 ) / 1.8
ºC = (18 – 32) / 1.8 = -7.77 ºC
K = ºC + 273
K = -7.77 + 273 = 265.23 K
T2 = 0.786 L x 265.23 K x 1.84 atm / 3.21 L x 0.045 atm
T2 = 2.65 L
3. V2 = V1 x P1 x T2 / P2 x T1
T1 = 120 + 273 = 393 K
V2 = 6.8 L x 2 atm. x 567 K / 1.5 atm. x 393 K
V2 = 13.08 L
4.
T1 = ?
V1 = 897 mL / 1000 = 0.897 L
P1 = 567 mmHg
1 atm --- 760 mmHg
X --- 567 mmHg
X = 0.746 Atm.
T2 = 60 + 273 = 333 K
P2 = 564 torr
760 torr ---- 1 atm
564 torr ---- x
X = 0.742 atm.
T1 = V1 x P1 x T2 / V2 x T2
T1 = 0.897 L x 0.742 atm. x 333 K / 0.746 atm. x 0.6541 L
T1 = 454 K
5.
V1 = ?
T1 = 74 + 273 = 347 K
P1 = 720 torr
760 torr ---- 1 atm
720 torr ---- x
X = 0.95 atm.
V1 = V2 x P2 x T1 / P1 x T2
V1 = 0.65 L x 0.98 atm. 247 K / 0.95 atm. x 280 K
V1 = 0.592 L
6.
T1 = 300 K
V1 = 589 mL / 1000 = 0.589 L
P1 = ?
T2 = 600 K
V2 = 984 ml / 1000 = 0.984 L
P2 = 1.2 atm.
P1 = V2 x P2 x T1 / V1 x T2
P1 = 0.984 L x 1.2 atm. x 300 K / 0.589 L x 600 K
P1 = 1.00 atm.
7.
T1 = ?
V1 = 2.871 L
P1 = 2,7 atm
T2 = 46.8 + 273 = 319,8 K
V2 = 10000 / 1000 = 10 L
P2 = 0.8 atm
T1 = V1 x P1 x T2 / V2 x P2
T1 = 2.871 L x 2.7 atm. x 319.8 K / 10 L x 0.8 atm.
T1 = 308.87 K
