Solved: A 19.2-g quantity of dry ice (solid carbon
Chapter 6, Problem 6.107(choose chapter or problem)
A 19.2-g quantity of dry ice (solid carbon dioxide) is allowed to sublime (evaporate) in an apparatus like the one shown in Figure 6.5. Calculate the expansion work done against a constant external pressure of 0.995 atm and at a constant temperature of 228C. Assume that the initial volume of dry ice is negligible and that CO2 behaves like an ideal gas.

QUESTION:
A 19.2-g quantity of dry ice (solid carbon dioxide) is allowed to sublime (evaporate) in an apparatus like the one shown in Figure 6.5. Calculate the expansion work done against a constant external pressure of 0.995 atm and at a constant temperature of 228C. Assume that the initial volume of dry ice is negligible and that CO2 behaves like an ideal gas.
ANSWER:Step 1 of 5
According to ideal gas law, the number of moles can be calculated by the following formula.
........................(1)
P = pressure
V = Volume
n = Number of moles
R = Gas constant
T = Temperature.
