The molarity of a solute in solution is defined to be the number of moles of solute per liter of solution (1 mole = 6.02 × 1023 molecules). if x is the molarity of a solution of magnesium chloride (mgcl2), and y is the molarity of a solution of ferric chloride (fecl3), the molarity of chloride ion (cl−) in a solution made of equal parts of the solutions of mgcl2 and fecl3 is given by m = x + 1.5y . assume that x has mean 0.125 and standard deviation 0.05, and that y has mean 0.350 and standard deviation 0.10.

a. find the mean of m
b. find the standard deviation of m (assume x and y are independent).
