Question

At 25 degree celsius and 730 mm pressure 380 ml of oxygen is collected in the temperature is constant what is the volume of oxygen occupy at 760 mm pressure

Answer 1

Explanation:

At constant temperature,for a fixed mass of gas,volume is inversely proportional to pressure.

PV=constant

Formula used :

P1V1=P2V2

Here,P1=730mm

P2=760mm

V1=730ml

V2=?

V2=P1V1/P2 =730×730/760 =532900760 =701.18ml
