Answer :
Final answer:
To convert the pressure of a gas sample from 0.827 atm to psi, we use the conversion factor 1 atm = 14.6959 psi. The answer is A. approximately 12 psi when rounded to the nearest whole number.
Explanation:
The question asks for the conversion of pressure from atmospheres (atm) to pounds per square inch (psi). Given that the pressure is 0.827 atm, we need to convert this value to psi. The conversion factor between atm and psi is 1 atm = 14.6959 psi. Therefore:
Pressure in psi = Pressure in atm × (Conversion factor from atm to psi)
Pressure in psi = 0.827 atm × 14.6959 psi/atm
Pressure in psi = 12.15 psi
When rounding to the nearest whole number, the pressure of the gas sample in psi is approximately 12 psi.
