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.

Respuesta :

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
