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 : 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.

or,

where,

= initial pressure = 760.00 mmHg

= final pressure = 850.00 mmHg

= initial volume = 45.00 mL

= final volume = ?

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

Thus, the  new volume is, 76.00 mL
