Question

The pressure exerted on a 254.5 mL sample of helium gas at constant temperature is increased from 0.4750 atm to 0.778 atm. Calculate the final volume of the sample.

Answer 1

155.382 mL

Step-by-step explanation:

Using Boyle's Law

P1V1=P2V2

P1= Initial Pressure

V1= Initial Volume

P2= Final Pressure

V2= Final Volume

0.4750 atm (254.5mL)= 0.778 atm (V2)

120.8875= 0.778 atm (V2)

V2= 155.382 mL
