I have an unknown volume of gas at a temperature of 115 K in a container with a pressure of 60 atm. If we increase the temperature to 225 K and decrease the pressure to 30 atm, which causes the volume to be 29 liters, how many liters of gas did I start with?

113.5 L

Explanation:

Use combined gas law and rearrange formula.

- Hope this helps! Please let me know if you need further explanation.

answer; i believe the correct answer is (solid gold);

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.
