Question

A gas has a volime of 45.00 mL and a pressure of 760.00 mm. If the pressure increased to 850.00 mm and the temperature stayed the same what is the new volume

Answer 1

Answer : The new volume is, 76.00 mL

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

`P\propto (1)/(V)`

or,

`P_1V_1=P_2V_2`

where,

`P_1` = initial pressure = 760.00 mmHg

`P_2` = final pressure = 850.00 mmHg

`V_1` = initial volume = 45.00 mL

`V_2` = final volume = ?

Now put all the given values in the above equation, we get:

`760.00mmHg* 85.00mL=850.00mmHg* V_2`

`V_2=76.00mL`

Thus, the new volume is, 76.00 mL
