Answer:
The new pressure of the gas is 395.5mmHg
Explanation:
The pressure of a gas is inversely proportional to its concentration (Boyle's law). The equation that explain this law is:
P₁V₁ = P₂V₂
Where P is pressure
And V is volume of 1, initial state and 2, final state of the gas
Initial state:
791mmHg; 0.500L.
Final state:
1.00L
Replacing:
791mmHg* 0.500L = P₂*1.00L
P₂ = 395.5mmHg
The new pressure of the gas is 395.5mmHg
