Problems Carry out the following calculations. 1. A cube of metal measures 2.2 cm on a side. It has a mass of 47.68 g. What is its density? 2. What is the volume of a 678-g sample of a substance that has a density of 11.3 g/mL? 3. The density of liquid iron is 7.05 g/mL. How many milli- liters of iron must be mixed with liquid chromium to make 1.00 kg of an alloy that is 72.0% by mass iron? 4. The temperature of a given liquid increases by 12.0°C if 69.0 joules of heat is added to a 20.0-g sample. What is the specific heat of the liquid?
