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.
