Use the exact values you enter to make later calculations. Consider the following figure. A Pb-Sn alloy contains 53.2% and 46.8% at 100C. Estimate the compositions (in wt %Sn ) of and at 100C. wt %Sn of wt %Sn of Determine the composition (in wt %Sn ) of the alloy. % Is the alloy hypoeutectic or hypereutectic? hypoeutectic hypereutectic
