To determine the partial pressure of carbon dioxide, we need to consider the total pressure and subtract the vapor pressure of water.
Total pressure = 760 mm Hg
Vapor pressure of water = 28 mm Hg
Partial pressure of carbon dioxide = Total pressure - Vapor pressure of water
Partial pressure of carbon dioxide = 760 mm Hg - 28 mm Hg
Partial pressure of carbon dioxide = 732 mm Hg
When heated at high temperature, sodium carbonate, Na2CO3, decomposes to sodium oxide and carbon dioxide gas. A sample of 587.3 mL gas was collected using water displacement method at 27 °C at a total pressure of 760 mm Hg and vapour pressure of water is 28 mm Hg.
Determine the partial pressure of carbon dioxide, CO2 released from the reaction.
