Question

which equation represents a solution for the temperature t in the equation below: pv = nrt t = pv/nr t=(pv)x(nr) t = pn/vr t = nr/pv question 39 1 pts an fossil specimen is found to be 65,200 years old. how many significant figures are there in this measurement? infinite three five four

Explanation:

Step1: Solve for T in PV = nRT

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

Step2: Determine significant - figures in 65,200

Non - zero digits are always significant. Trailing zeros in a number without a decimal point may or may not be significant. Here, 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:

1. T = PV/nR
2. three
