Application of Boyle's Law.
A gas occupying a volume of 725 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final volume?
Molecular formula of a compound
A compound of P and F was analyzed as follows: Heating 0.2324 g of the compound in a 378-cm cubed container turned all of it to gas, which had a pressure of 97.3 mmHg at 77 degrees C. Then the gas was mixed with calcium chloride solution, which turned all of the F to 0.2631 g of CaF2 . Determine the molecular formula of the compound.following
