Consider a random mixture containing particles of Na2SO4 and K2SO4. There are 4.88 g of Na2SO4 (density 2.681 g/mL) and 95.12 g of K2SO4 (density 2.500 g/mL) in the mixture. All particles in the mixture have a uniform spherical radius of 0.072 mm. a) Calculate the mass of a single particle of Na2SO4 and the number of Na2SO4 particles in the mixture.
