Question

103 ml of co2 were collected at 27 degree Celsius and 763mm pressure what will be it's volume if the pressure is changed to 721mm at the same temperature

Answer 1

according to BOYLE'S law of an ideal gas. at constant temperature, pressure is inversely proportional to volume of gas. e.g., $PV=K$

or, $P_1V_1=P_2V_2$

given, initial volume of CO2 gas , $V_1=103ml$

initial pressure of CO2 gas, $P_1$ = 763 mm Hg

final pressure of gas, $P_2$ = 721 mm Hg

now, 103ml × 763 mm Hg = $V_2$ × 721mm Hg

or, $V_2$ = 103 × 763/721

= 109 ml

hence, answer is 109 mL
