 * //Robert Boyle//**

Was born on January 25, 1627 and died on December 30, 1691 Born in Lismore, County Waterford, Ireland Was an Anglo Irish physicist and chemist Known as the Father of Modern Chemistry Invented a gas pump which helped him discover what is known as Boyle’s Law He separated chemistry from alchemy He was the 1st to give definitions of chemical element, reaction, and analysis He contributed to the atomic theory of matter ** This law was developed in 1662. It states that the pressure on volume of a gas is inversely proportional to the other. His invention of the gas pump helped to create his law. The equation fro this law is P1V1=P2V2
 * Boyles Law:

**Question:** A sample of oxygen gas has a volume of 150.0 ml when its pressure is 0.947 atm. What will the volume of the gas be at a pressure of 0.987 atm if the temperature remains constant? **Given:** V1 of O2 = 150.0ml P1 of O2 = 0.947atm P2 of O2 = 0.987 atm **Unknown:** V2 of O2 in ml Equation: P1V1 = P2V2 V2 = P1V1 _________     P2    V2 = ( 0.947atm)(150.0ml of O2)  = 142.05ml of O2 = **//143.9 0r 144ml of O2//** __________________________________ ___________________    ( 0.987atm) 0.987
 * THE ATMS CANCEL LEAVING JUST THE ML OF O2 **
