The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the pressure when its volume is changed to 2.00 L? Use mc004-1.jpg. 0.225 atm 0.444 atm 2.25 atm 4.44 atm

This is a question on the relationship between volume and pressure.
FORMULA
P₁V₁ = P₂V₂
Where P is pressure and V is volume.
Convert the litres to ml.
2.0 × 1000 = 2000ml
Substituting in the formula :
450 × 1 = 2000 × P₂
P₂ = 450/2000
P₂ = 0.225 atm
The pressure is thus 0.225 atm
