If the pressure of a gas is 2.42 atm, what is its pressure in kPa?
A
245.2 kPa
B
245 kPa
C
245.3 kPa
D
245.0 kPa
Verified step by step guidance1
Identify the given pressure in atmospheres (atm), which is 2.42 atm in this problem.
Recall the conversion factor between atmospheres and kilopascals: 1 atm = 101.325 kPa.
Set up the conversion equation to convert pressure from atm to kPa: \(P_{kPa} = P_{atm} \times 101.325\).
Substitute the given pressure value into the equation: \(P_{kPa} = 2.42 \times 101.325\).
Perform the multiplication to find the pressure in kPa (do not calculate the final value here, just set up the expression).
