Concept Introduction:
Mole is the unit for calculating large quantities of small units, such as atoms and molecules.
Carbon dioxide is a colorless and odorless gas.
A small amount of carbon dioxide is essential for sustaining life on the earth.

Answer to Problem 50E
Solution:
a)
The number of moles of
b)
The volume of
c)
The number of years required to double the amount of
Explanation of Solution
a) Number of moles of
The amount of
The reaction is as follows:
The equation for the reaction of
The mass of
The moles of
Substitute the value of given mass and molecular mass in the above expression.
From the above equation, 2 moles of
Hence, the number of moles
b) The volume occupied by number of moles of
1 mole of gas occupies 22.4L.
The volume of
Substitute the value of moles of
Hence, the volume of
c) The number of years it will take to double the amount of
The volume of
The volume of
Substitute the volume of
Hence, the number of years it will take to double the amount of
