Answer 1

1.

1 torr =

1 mm Hg ≈

0.00132 atm ≈

133 pasc

265 torr =

265 mm Hg =

0.348684 atm =

35330.4

2.

P • V = n • R • T

a.

V = 2,46M • 0,0082 atm•L/(M•K) • 267K / 1,28atm

V ≈ 42,078L

b.

T = 0,947atm • 0,135L/(4,79×10⁻²M • 0,082 atm•L/(M•K))

T ≈ 32,549K

c.

P = 5,52×10⁻²M • 0,082 atm•L/(M•K) • 361K / 0,413L

P ≈ 3,956 atm

d.

n = 88,4L • 0,0971 atm /(0,082 atm•L/(M•K) • 327K)

n ≈ 0,320M

3.

n = 0,082 atm•L/(M•K) • 297K / (1,479 atm • 9,22L)

n = 1,786M

a.

2×35,45g/M = X/1,786M

X ≈ 126,627g

b.

V = 1,786M • 0,082 atm•L/(M•K) • 273K / 1 atm

V ≈ 39,981L

c.

T = 1,153 atm • 15L /(1,786M • 0,082 atm•L/(M•K))

T ≈ 118,093K

d.

P = 1,786M • 0,082 atm•L/(M•K) • 331K / 6L

P ≈ 8,079 atm

4.

T = 2,2 atm • 0,25L / (0,5M • 0,082 atm•L/(M•K))

T ≈ 13,415K = -259,585°C
