You have a sample of carbon dioxide at 298 K. If the pressure is 0.827 atm, what is the pressure of your gas sample in psi?

A. 12.0 psi
B. 20.0 psi
C. 8.27 psi
D. 5.65 psi

Answer :

Final answer:

The pressure of the carbon dioxide gas sample at 0.827 atm is converted to psi using the conversion factor 1 atm = 14.6959 psi. After calculation, the result is approximately 12.1 psi; thus, the closest given answer is 12.0 psi.

Explanation:

The question involves converting the pressure of a gas sample of carbon dioxide from atmospheres (atm) to pounds per square inch (psi). The conversion factor for atm to psi is 1 atm = 14.6959 psi. Using this conversion factor, we can perform the calculation to find the pressure in psi:

Pressure in atm x (conversion factor) = Pressure in psi

0.827 atm x 14.6959 psi/atm = 12.148 psi

We round this value to the nearest tenth as is common in chemistry calculations, yielding a result of 12.1 psi, which is not one of the options provided. The closest option to our calculated result is (a) 12.0 psi.
