of water at this tempera 1.16 The density of platinum is 21.5 g/cm' at 25°C. What is the volume of 87.6 g of Pt at this temperature? 1.17 Convert the following temperatures to kelvins: (a) 113°C, the melting point of sulfur; (b) 37°C the normal body temperature; (c) 357°C, the boiling point of mercury. 1.18 Convert the following temperatures to degrees Celsius: (a) 77 K, the boiling point of liquid nitrogen; (b) 4.2 K, the boiling point of liquid helium; (c) 601 K, the melting point of lead. 1.19 A 18.5-g sample of lead pellets at 20°C is mixed with a 45.8-g sample of lead pellets at the same temperature. What are the final mass, temperature, and density of the combined sample? (The density of lead at 20°C is 11.35 g/cm. Assume no heat is lost to the surroundings.) A student pours 61.1 g of water at 10°C into a beaker containing 95.3 g of water at 10°C. What are the final mass, temperature, and density of the combined water?
