The table shows the masses of metals found by analysing a sample of an alloy.
| Metal | Mass in the sample (g) |
|---|---|
| Tin | 47.0 |
| Copper | 2.0 |
| Silver | 1.0 |
Calculate the percentage by mass of tin in the sample.
Show your working.
Name the alloy.
Explain why this alloy is suitable for joining electrical components that are easily damaged by heating.
