Question

Determine the volume of \({\rm{1 mol}}\)\({\rm{of}}\)\({\rm{C}}{{\rm{H}}_{\rm{4}}}\) gas at \({\rm{150 K}}\) and \({\rm{1 atm}}\), using Figure 9.12 .

Short answer

The volume of 1 mol of \(C{H_4}\)is 12.5 L at 150 K temperature and 1 atm pressure..

Step-by-step solution

Defining volume

The volume of a substance is the amount of space it takes up, whereas its mass is the quantity of matter it contains.

Explanation

Figure \({\rm{9}}{\rm{.12}}\)depicts the relationship between methane’s volume and temperature when the quantity is \({\rm{1 mol}}\)and the pressure is\({\rm{1 atm}}\). These are the conditions that occur in the issue as well. We may easily deduce from the graph what volume of methane would fill at \({\rm{150 K}}\)under these conditions.

Therefore, therequired value is\({\rm{12}}{\rm{.5 L}}\).
