Question

In order to calculate the relative sampling standard deviation for each particle type, we divide the standard deviation in the sampling method by the expected number of each particle type. standard deviation in sampling operation=Vnpq where n is the number of particles in the sample, p is the probability of drawing type A particles, and q is the probability of drawing type B particles. If there were 2.30 x 105 Na2SO4 particles and 21600000 K2SO4 particles in the original 100.00 g mixture, determine the probability of drawing each type of particle from the mixture. Number p=probability |0 of drawing Na,SO,- Number q probability of drawing K,SO,
