The molarity of a solute in solution is define to be the number ofmoles of solute per liter of solution (1mole = 6.02 e23 molecules). if x is the molarity of a solution of sodium chloride(nacl),and y is the molarity of a solution of sodium carbonate (na2co3),the molarity of sodium ion (na+) in a solution made of equal partsnacl and na2co3 is given by m = 0.5x + y.
assume x and y areindependent and normally distributed, and that x has mean 0.450 andstandard deviation 0.050, and y has mean of 0.250 and standarddeviation 0.025.
a) what is the distribution of m?
b) find p(m > 0.5).
