Question

POSSIBLE POINTS: 1Dryice is carbon dioxide in the solid state. 1.28 moles of dry ice is placed in a 5.00 L chamber that is maintained at 35.10C. What is the pressure in thechamber after all of the dry ice has subiimed (atm)?O 6.5 atmO 6.0 atmO 6.8 atmO 5.8 atm

Answer 1

6.5atm

Explanations:

According to the ideal gas equation:

`PV=nRT`

where:

• P is the ,pressure ,of the gas

,

• V is the ,volume

,

• n is the ,number of moles

,

• R is the ,gas constant

,

• T is the, temperature

Given the following parameters

V = 5.00L

n = 1.28moles

T = 35.10 + 273 = 308.1K

R = 0.08205Latm/molK

Substitute the given parameters into the formula

`\begin{gathered} P=(nRT)/(V) \\ P=(1.28*0.08205*308.1)/(5.0) \\ P=(32.3579)/(5.0) \\ P\approx6.5atm \end{gathered}`

Hence the pressure in the chamber after all of the dry ice has sublimed is 6.5atm
