A gas is at a pressure of 12.5 psi and a volume of 750 mL. What volume will the gas occupy at a pressure of 18 psi?

Answer : The volume of gas occupy at a pressure of 18 psi is, 520.8 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 = 12.5 psi

= final pressure = 18 psi

= initial volume = 750 mL

= final volume = ?

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

Thus, the volume of gas occupy at a pressure of 18 psi is, 520.8 mL

b is the correct answer

mark me brainliest and hope this

answer: mole of the gas

answer: mole of the gasexplanation:
