    Explanation:

    Given data

    Mass of O₂ (m) : 2.50 * 10³ g Volume (V) : 10.0 L Temperature (T) : 20.0°C + 273.15 = 293.2 K

    The molar mass of O₂ is 32.00 g/mol. The moles of O₂ are:

    2.50 * 10³ g * (1 mol / 32.00 g) = 78.1 mol

    We can find the pressure exerted by the oxygen using the ideal gas equation.

    P * V = n * R * T

    P = n * R * T / V

    P = 78.1 mol * (0.0821 atm. L/mol. K) * 293.2 K / 10.0 L

    P = 188 atm
