Questions 1. What maximum temperature is 90% gold alloy remains to be pure solid? 2 Calculate the molar (atomic) percentage of this alloy if 25% of its mass (welght) is silver at 1000°C. 3. At 960°C how much mass of silver must be added to gold, with a mass of 156 grams, to attain 35% gold? 4. Does this system display peritectic transformation? Why?
