Answer to Question #111084 in General Chemistry for Sophia

Question

In a fit of boredom, a chemistry teaching
assistant swallows a small piece of solid dry
ice (CO2). The 9.6 g of dry ice are converted
very quickly into gas at 311 K. Assuming the
TA’s stomach has a volume of 1.5 L, what
pressure is exerted on his stomach?
Answer in units of atm.

Answer 1

pV=nRT.

p=nRT/V= 0.218181818 x 0.082 x 311 / 1.5 = 3.70938182 atm.
