If 4 moles of a gas are removed from a container that previously held 8 mole of gas, how will the pressure change within the container? (Assume that volume and temperature remain constant.)The pressure will go up four times.b.The pressure will be cut in half.c.The pressure will be doubled.d.The pressure will go down four times.

Respuesta :

Answer:

b. The pressure will be cut in half.

Explanation:

As we can see in the Ideal Gases formula, the pressure and the number of moles are directly proportional:

[tex]P*V=n*R*T[/tex]

if the temperature and volume remain constant, when extracting 4 moles, the amount of substance inside the container decreases, that is, there are fewer particles, therefore the pressure will be lower.

When the number of moles is cut in half (from 8 moles to 4 moles), the pressure will also be cut in half.
