1 grain = 103g
2kg = 2000g
grains = 2000g/103g = 19.417
Answer:
About 19.417 grains

For margin of error to be a maximum of 3:
3 = z*(SD / sqrt(n)), where z is the z-score, SD is the standard deviation and n is the sample size.
z = 1.96 for a 95% confidence interval, and we are given SD = 15.
3 = 1.96*15/sqrt(n)
sqrt(n) = 9.8
n = 96.04 ~ 96 commercials.
True! they are corresponding angles.
