A gas has a volume of 400 mL at 50.0 °C and 120 kPa. What will be its volume at a temperature of 80.0 °C and a pressure of 180 kPa?

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?

How many grams are in 1.75 mile of carbon
