Question
Chapter 20, Problem 32QAP
Interpretation Introduction
Interpretation:
The mass of KO2 that is left after the water in exhaled air reacts with it should be calculated.
Concept introduction:
The moles of any compound or element can be calculated by given formula:
Where n is number of moles, m is the given mass and M is molar mass.
To obtain the volume of gases, the ideal gas equation is used as:
Where P is pressure, T is temperature, n is number of moles, R is gas constant, and V is volume of gas.
Actually, in breathing apparatus the exhaled air contains carbon dioxide and water.
The KO2 first reacts with water to form potassium hydroxide which later removes carbon dioxide by forming KHCO3.
The reactions are as follows:
