Question

A gas sample has a volume of 300.0 L when under a pressure of 3atm. What is the

new volume iſ the pressure is increased to 4 atm while the temperature is held
constant?
200L
225L
300L
900L

Answer 1

V1P1=V2P2

300*30=x*40

900=40x

decide both side by 40to be left by volume x

900÷40=x

x=225L
