ideal

The idea gas law is also used to calculate the changes that will occur when the conditions of the gas are changed. PV=nRT


 * PROBLEM:**A SAMPLE OF HYDROGEN GAS HAS A VOLUME OF 8.56 L AT A TEMP. OF 0C AND A PRESSURE OF 1.5 ATM . CALCULATE THE MOLES OF H2 MOLECULES PRESENT IN THIS GAS SAMPLE.

P=1.5 ATM V=8.56 L T= 0C +273= 273K R= .O8206 L

n=(1.5)(8.56)/(.08206)(273)=.57 MOL
