    Answer: 2.58L

    Explanation:

    We must convert the temperature from °C to Kelvin temperature

    T1 = 40°C = 40 + 273 = 313K

    V1 = 2.32 L

    T2 = 75°C = 75 + 273 = 348K

    V2 = ?

    V1 / T1 = V2 / T2

    2.32 / 313 = V2 / 348

    Cross multiply to express in linear form

    313 x V2 = 2.32 x 348

    Divide both side by the coefficient of V2 ie 313. We have

    V2 = (2.32 x 348) / 313

    V2 = 2.58L

    Therefore, if the temperature is raised to 75°C, the volume of the gas will be 2.58L
