A piece of metal having a density of 19.3 g/mL when dropped into a graduated cylinder...
A 24.32 g piece of metal is dropped into a graduated cylinder with 144.1 mL of water. If the density of the metal is 4.81 g/cm3, what is the total volume in the graduated cylinder in mL with the correct number of significant digits?
A 50 mL graduated cylinder contains 25.0 mL of water. A 42.5040 g piece of gold is placed in the graduated cylinder and the water level rises to 27.2 mL. What is the density of the piece of gold? (a) 19.3 g/mL (b) 15.6 g/mL (c) 5.90 g/mL (d) 12.3 g/mL (e) 3.63 g/mL
A piece of gold metal is heated from 25C to 90C. It is then dropped into 1 litre of water at 25.0 o C and the water temperature increases to 25.4 o C. The heat capacity of gold is 0.129 J K-1 g -1 and that of water is 4.18 J K-1 g -1. (A) what is the mass of gold sample (b) what is the entropy change in the gold as it is heated up? (c) assume that water...
2. 19.54 grams of a metal with density 4.88 g/mL is placed into a graduated cylinder originally with 20.5 mL of water in it. What is the final volume reading on the cylinder? a. 24.5 mL b. 40.0 mL c. 75.4 mL d. 95.4 mL
A 42.1 g piece of metal was heated to 95.4°C and then dropped into a beaker containing 42.0 g of water at 23.00°C. When the water and metal come to thermal equilibrium, the temperature is 32.10°C. What is the specific heat capacity of the metal? The specific heat capacity of the water is 4.184 J/(g-K). 0.387 J/(g-K) 0.600 J/(g-K) 0.488 J/(g-K) 0.720 J/(g-K) 0.980 J/(g-K) Previous Page Next Page Page 22 of 24 Submit Quiz 0 of 24 questions saved
A piece of metal ore has a density of 5.15 g/cm3. When a student places an 11.5g sample into a graduated cylinder containing 15.0 mL of water. What will be the final reading of the water volume on the graduated cylinder once the ore is placed in the water? Your answer must have the correct number of significant figures?
An irregular lump of an unknown metal has a measured density of 3.84 g/mL. The metal is heated to a temperature of 161 °C and placed in a graduated cylinder filled with 25.0 mL of water at 25.0 °C. After the system has reached thermal equilibrium, the volume in the cylinder is read at 33.7 mL, and the temperature is recorded as 37.4 °C. What is the specific heat of the unknown metal sample? Assume no heat is lost to...
