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
NikAS [45]

Answer: 0.225 atm

Explanation:

For this problem, we have to use Boyle's Law.

Boyle's Law: P₁V₁=P₂V₂

Since we are asked to find P₂, let's manipulate the equation.

P₂=(P₁V₁)/V₂

P_{2} =\frac{(1.00atm)(0.45L)}{2.00L}

With this equation, the liters cancel out and we will be left with atm.

P₂=0.225 atm
