A gas occupying a volume of 1.50 L exerts a pressure of 700 mmHg at 200°C.Which mathematical expression gives the correct pressure at 6.00 L and 400°C?

We can use the combined gas law to solve this problem:

(P1V1/T1) = (P2V2/T2)

Plug in the given values:

(700 mmHg)(1.50 L)/(473 K) = (P2)(6.00 L)/(673 K)

Solve for P2:

P2 = (700 mmHg)(1.50 L)(673 K)/(6.00 L)(473 K) = 1500 mmHg

Therefore, the correct pressure at 6.00 L and 400°C is 1500 mmHg.

The answer is B because only choice B gives the value of 1500 mmHg.
