The partial pressure of gas X is equal to (B+C)-800.
We can use Dalton's law of partial pressures to solve this problem. Dalton's law states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases. In this case, we have three gases, X, Y, and Z, and we know that their total pressure is 800 torr. We are asked to find the partial pressure of gas X.
We can represent Dalton's law mathematically as follows:
P_total = P_1 + P_2 + P_3 + ...
where:
P_total is the total pressure of the mixture
P_1, P_2, P_3, ... are the partial pressures of the individual gases
We are given that the total pressure of the mixture is 800 torr. We are also given that the partial pressure of gas Y is B torr and the partial pressure of gas Z is C torr. We can substitute these values into the equation above to get:
800 torr = P_x + B torr + C torr
We can rearrange the equation to solve for P_x:
P_x = 800 torr - B torr - C torr
P_x = (B+C)-800 torr
Therefore, the partial pressure of gas X, in torr, is equal to (B+C)-800.
