Electronic solder is an alloy of tin and lead. Determine the composition of this solder alloy. Answer in % lead (by mass). Here is the data:
Density of pure lead: 11.4 g/cm^3
Density of pure tin: 7.31 g/cm^3
Density of solder sample: 10.35 g/cm^3
Remember find the % lead by MASS.
1. 65.98 % lead by mass
2. 74.32 % lead by mass
3. 77.95 % lead by mass
4. 78.27 % lead by mass
5. 81.9 % lead by mass
Let us take 1 cc of the solder sample. This sample weighs 10.35 g.
Let x grams be the weight of pure lead and y grams be the weight of pure tin in the sample. Then we ...
