1. The problem statement, all variables and given/known data This question has got me REALLY confused. I'll be thankful for any help. I don't even know where to start, though I'll mention what my thoughts were. Q. A jeweller wishes to harden a sample of pure gold by mixing it with some silver so that the mixture contains 5.0% silver by weight the jeweller melts some pure gold and then adds the correct weight of silver. the initial temperature of the silver is 27 °C. Use the data given to calculate the initial temperature of the pure gold so that the final mixture is at the melting point of pure gold. Data. Melting point for gold, 1340 K. Melting point for silver, 1240 K. Specific heat capacity for gold (solid or liquid), 129 J kg-1 K-1. Specific heat capacity for silver (solid or liquid), 235 J kg-1 K-1. Specific latent heat of fusion for gold, 628 kJ kg-1. Specific latent heat of fusion for silver, 105 kJ kg-1. 2. Relevant equations The only two equations I suppose I know I can use here are: E=mcΔθ and E=mL 3. The attempt at a solution The first and last thought that came to my mind and that I wrote down while I was trying to answer the question was, 'Assuming the gold weights 9.5kg and the silver weighs 0.5kg.' And after that I was stuck. Where do I start from? I'd love to be able to solve this myself but unfortunately I don't know what to do with the data or how to use use it. Could someone please help? Edit: I have the answer if anyone needs it to confirm their solution.
