검증된 단계별 안내1
Identify the given pressure in atmospheres (atm), which is 0.830 atm in this problem.
Recall the conversion factor between atmospheres and kilopascals: 1 atm = 101.3 kPa.
Set up the conversion by multiplying the given pressure by the conversion factor: \(0.830 \, \text{atm} \times \frac{101.3 \ \text{kPa}}{1 \ \text{atm}}\).
Perform the multiplication to find the pressure in kPa (do not calculate the final value here, just set up the expression).
Interpret the result as the atmospheric pressure in Denver expressed in kilopascals (kPa).
