6) Suppose you have 100.00 ml of a solution of a dye and transfer 2.00 ml of the solution to a 100.00 ml volumetric flask. After adding water to the 100.00 ml mark, you take 5.00 ml of that solution and again dilute to 100.00 ml. If you find the dye concentration in the final diluted sample is 0.000158 M, what was the dye concentration in the original solution

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.
