Question

Use ideal gas law

A 1.72 L flask is filled with 1.03 g of some gas (molar mass 41.226g/mol) at 37.4°C. A different
unknown vapor (molar mass 24.502g/mol) is then added to the same flask until the total pressure is
2.263 atm. What is the mass of unknown gas (in grams) that was added to the flask?
Use 0.08206 L. atm · K1. mol1 for your gas constant.

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
