Answer

Question 38

Explanation:

Step1: Isolate T in PV = nRT

Divide both sides by nR. $T=\frac{PV}{nR}$

Answer:

T = PV/nR

Question 39

Explanation:

Non - zero digits are always significant. Trailing zeros in a number without a decimal point may or may not be significant. In the number 65200, the non - zero digits 6, 5, and 2 are significant. The two trailing zeros are not significant as there is no decimal point. So there are three significant figures.

Answer:

three
