  • Calculating Gas Pressure: A Step-by-Step Guide Using the Ideal Gas Law
    Here's how to determine the pressure exerted by the gas using the ideal gas law:

    1. Convert Temperature to Kelvin

    * The ideal gas law requires temperature in Kelvin.

    * K = °C + 273.15

    * K = 32.0 °C + 273.15 = 305.15 K

    2. Ideal Gas Law

    * The ideal gas law is: PV = nRT

    * P = Pressure (in atmospheres, atm)

    * V = Volume (in liters, L)

    * n = Number of moles

    * R = Ideal gas constant (0.0821 L⋅atm/mol⋅K)

    * T = Temperature (in Kelvin, K)

    3. Solve for Pressure (P)

    * Rearrange the ideal gas law to solve for P:

    * P = (nRT) / V

    4. Plug in the Values

    * P = (1.80 mol * 0.0821 L⋅atm/mol⋅K * 305.15 K) / 2.92 L

    5. Calculate the Pressure

    * P ≈ 15.3 atm

    Therefore, the pressure exerted by the gas is approximately 15.3 atmospheres.
