1.	103 mL of carbon dioxide were collected at 27^(@)C and 763 mm pressre. What will be its volume if the pressure is changed to 721 mm at the same temperature ?
Answer» Solution :`{:("GIVEN Conditions","Final Conditions"),(V_(1)=103 mL,V_(2)=?mL),(P_(1)=763 mm,P_(2)=721 mm):}` By applying Boyle's Law since temperature is constant, `P_(2)xxV_(2)=P_(1)xxV_(1)`. Substituting the corresponding values, we have `721xxV_(2)=763xx103,V_(2)=(763xx103)/(721)=109 mL:.` Volume of carbon dioxide=109 mL.
