A tank of N_2O has a pressure of 45.0 psi. What is this pressure in atmospheres (atm)? (1 atm = 14.7 psi)

• A. 0.33 atm
• B. 3.06 atm
• C. 1.53 atm
• D. 659 atm

Answer: (B)

Verified step by step guidance

1. Identify the given pressure in psi and the conversion factor to atm. Here, the pressure is 45.0 psi and 1 atm = 14.7 psi.
2. Write the conversion formula to convert pressure from psi to atm: \(P_{atm} = \frac{P_{psi}}{14.7}\).
3. Substitute the given pressure value into the formula: \(P_{atm} = \frac{45.0}{14.7}\).
4. Perform the division to find the pressure in atmospheres (atm).
5. Compare the calculated value with the given options to select the correct pressure in atm.
