Asample of gas has a volume of 135 ml at 0.600 atm. what would be the volume if the pressure is decreased to 0.200 atm while temperature is held constant? 405 ml 101 ml 180 ml 135 ml 45.0 ml

-

405 mL

Explanation: -

Initial Pressure P 1 = 0.6 atm

Final Pressure P 2 = 0.2 atm

Initial volume V 1 = 135 mL

Using Boyle's Law,

At constant temperature,

P 1 x V 1 = P 2 x V 2

0.6 atm x 135 mL = 0.2 atm x V 2

Final volume = V 2 =

= 405 mL

Thus if a sample of gas has a volume of 135 ml at 0.600 atm. 405 mL would be the volume if the pressure is decreased to 0.200 atm while temperature is held constant.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
