Question

Given, 6.2 atm is equal to how many torr?

Answer 1

Hint: The answer is dependent on the basic concept of chemistry which deals with the conversion factors and by using the conversion factor 1 atm = 760 torr, you will get the required answer.

Complete step by step solution:
The concept of various conversion factors such as degree Celsius to Kelvin, joules to calories and many other factors are familiar to us.
Let us see the basic conversion of the atmosphere to torr.
- We have the basic idea of the meaning of atmosphere that is nothing but the units used for measuring the pressure of the gas.
- Normal atmospheric pressure is defined as 1 atmosphere or 1 atm. This value in terms of psi is given by 1 atm = 14.6956 psi which is equal to 760 torr.
- This value is based on the original Torricelli barometer design where one atmosphere of pressure will force the column of mercury in a mercury barometer to a height of 760 millimeters.
Thus, 1 atm = 760 torr which means that we can calculate the conversion of 6.2 atm.
- Now, this conversion is simply the multiplication of atmospheric value with that of 760 torr. This value would be,
\[6.2\times 760=4712torr\]
Therefore, the correct answer is 6.2 atm is equal to 4712 torr.

Note:
Note that one unit of gas pressure is the millimetre of mercury (mmHg) and an equivalent to mmHg is called as the torr and the measure of pressure is also done by ‘Pascal’ and ‘psi’ is in pounds of force per square inch of area.
