1 determine the milligrams of ascorbic acid per gram of the tablet for each of the four trials.calculate the average milligrams of ascorbic acid per gram of tablet analyzed and determine the standard deviation .

2 using mean and standard deviation , determine a.milligrams of ascorbic acid per tablet. b. cost per gram of ascorbic acid .

Answer 1

standard deviation = 1/2(X-Xavg)/N

Here, X = 35 + 45+ 40 = 120

Xavg= 120/3 = 40

and N = 3

SD= 1/2(120-40)

= 80
