260K

Explanation:

We use the general gas equation to solve this. The mathematical form can be represented as follows:

P1V1/T1 = P2V2/T2

We are to look for T2 from the question, rearranging the equation yields:

T2 = T1P2V2/P1V1

So what information do we have from the question:

T2=?

P2 = 640mmHg

V2 = 198L

P1 = 760mmHg

T1 = 273K as they gas is at S. T. P since pressure is 760mmHg which is the standard pressure

V1 = 175L

We now substitute all these values:

T2 = (273 * 640 * 198) / (760 * 175)

T2 = 260K
