In the notation of Exercise 49, assume that a measurement yields V = 4. Estimate the maximum allowable error in V if P must have an error of less than 0.2 atm.

Data From Exercise 49

The volume (in liters) and pressure P (in atmospheres) of a certain gas satisfy PV = 24. A measurement yields V = 4  with a possible error of ±0.3 L. Compute P and estimate the maximum error in this computation.
