Consider a random mixture containing particles of Na2SO4 and K2SO4. There are 5.32 g of Na2SO4 (density 2.639 g/mL) and 94.68 g of K2SO4 (density 2.456 g/mL) in the mixture. All particles in the mixture have a uniform spherical radius of 0.094 mm. a) Calculate the mass of a single particle of Na2SO4 and the number of Na2SO4 particles in the mixture.
Explain the large disparity in the numerical results pf Part (a). Discuss the advantages and disadvantages of the three energy sources.
