A magnesium-lead alloy of mass 6.4 kg consists of a solid a phase that has a composition just slightly below the solubility limit
at 300°C (570°F). The magnesium-lead phase diagram is shown in Animated Figure 9.20.
(a) What mass of lead is in the alloy?
i
kg
(b) If the alloy is heated to 400°C (750°F), how much more lead may be dissolved in the a phase without exceeding the
solubility limit of this phase?

For alloys of two hypothetical metals A and B, there exist an a, A-rich phase and a ß, B-rich phase.
From the mass fractions of both phases for two different alloys (given below), which are at the same temperature, determine
the composition of the phase boundary (or solubility limit) for the following:
