A student produces carbon dioxide gas by heating calcium carbonate in a flask. She collects the gas by bubbling it into a test tube inverted in water. After filling the test tube, the student measures the pressure of the test tube's contents as 100.6 kPa at a temperature of 24.0°C. Find the partial pressure of carbon dioxide in the test tube. The partial pressure of water vapor at 24.0°C is 2.98 kPa.

    The partial pressure of Carbon dioxide is 97.6 kPa

    Explanation:

    given:

    partial pressure of water vapor P (water vapor) = 2.98 kPa

    partial pressure that is involved totally P (total) = 100.6 kPa

    To find the partial pressures of compound we have the formula,

    P total = P1 + P2 + ... Pn

    Pressure (CO2) = Pressure (TOTAL) - Pressure (H2O)

    100.6 kPa - 2.98 kPa = 97.6 kPa
