1) A pressure of 1.25 atm is the same as a pressure of __________ of mm Hg. 2) W

Question

1) A pressure of 1.25 atm is the same as a pressure of __________ of mm Hg.

2) What is the pressure (atm) of the enclosed gas in (i)? Assume that the gray liquid is mercury. use 2 decimal places

A)Calculate the volume the gas will occupy if the pressure is increased to 1.86atm while the temperature is held constant. (in liters)

B)Calculate the volume the gas will occupy if the temperature is increased to 180

?C while the pressure is held constant. (in liters)

A pressure of 1.25 atm is the same as a pressure of __________ of mm Hg. What is the pressure (atm) of the enclosed gas in (i)? Assume that the gray liquid is mercury. use 2 decimal places

Explanation / Answer

1) 1.25 atm = 1.25 x 760 = 950 mm of Hg

2) Enclosed gas in 1 has a pressure of 1 atm

Enclosed gas in (ii),

P = 1 atm + 670 mm of Hg = 1.882 atm

3) P1V1 = P2V2

=> 759 x 5.22 = 1.86 x 760 x V2

=> V2 = 2.803 L

V1 / T1 = V2 / T2

=> 5.22 / 296 = V2 / 453

=> V2 = 7.989 L
