Specific heat of a substance is the heat required to increase one gram of the substance by 1 °C.
Specific heat values in J/g°C for the given metals are:
Copper: 0.386, Iron: 0.450, Gold: 0.129, silver: 0.233
So, the order of the metals from highest to lowest specific heat is:
Iron
Copper
Silver
Gold

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1659 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 11.76 mL of the standard solution. What...
