Determine the value of x in the following equation if P2 is 296.

Question

Express your answer with three (3) significant figures.  ln(P2/760)=40700/8.314(1/373−1/x)

Answer 1

If P²=296, then ln(P²/760)=ln(296/760)=ln(37/95)=-0.943 approx.

If you mean ln(P²/760)=(40700/8.314)(1/373-1/x), then:

-0.943=4895.357(0.002681-1/x),

0.002681-1/x=-0.0001926,

1/x=0.002681+0.0001926=0.002874, x=1/0.002874=348.

There are other approaches to the solution, but all will produce x=348 (correct to 3 sig figures).
