A sample of chlorine gas occupies a volume of 775 mL at a pressure of 545 mmHg. Calculate the pressure of the gas (in mmHg) if the volume is reduced at constant temperature to 171 mL. Enter your answer in scientific notation.

Answer : The final pressure of the gas is,

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 = 545 mmHg

= final pressure = ?

= initial volume = 775 mL

= second volume = 171 mL

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

Therefore, the final pressure of the gas is,
