Would you please tell me if these are right?
A sample of helium has a volume of 325 ml and a pressure of 655 mm hg. What will be the pressure if the helium is compressed to 125 ml (t and n are constant)
I got 1703 mm of Hg
A 75.0 ml sample of oxygen has a pressure of 1.50 atm. what will be the new volume if the pressure becomes 4.50 atm? (t and n constant)
I got 25 mL.
In a weather report, the atmospheric pressure is given as 29.4 inches of Hg. what is the corresponding pressure in mm Hg?
I got 735 mm
