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

LuckyWell [14K]

There are no states in the picture, but Na should have a "(s)" after it, and Cl2 should have a "(g)" after it. NaCl should have an "(s)". Chlorine is a diatomic element so it has a "2" subscript on it.

Hope this helped! :)
