Question:

Consider a random mixture containing 4.00 g of Na2CO3 (density 2.532 g/mL) and 96.00 gof K2CO3 (density 2.428 g/mL) with a uniform spherical particle radius of 0.075 mm.
(a) Calculate the mass of a single particle of Na2CO3 and the number of particles of Na2CO3 in the mixture. Do the same for K2CO3.
(b) What is the expected number of particles in 0.100 g of the mixture?
(c) Calculate the relative sampling standard deviation in the number of particles of each type in a 0.100-g sample of the mixture.
