2. 19.54 grams of a metal with density 4.88 g/mL is placed into a graduated cylinder...
A metal object weighting 1025.6 g is placed in a graduated cylinder containing 156.8 mL of water. The volume increases to 236.8 mL. Calculate the density of the metal.
8.5 g of metal is placed in a graduated cylinder containing water. The level of water increases from 40.0 ml to 44.5 ml. The density of the metal is _____ g/ml? (Use the correct number of significant figures in your answer)
A 25.5 g sample of a metal was placed into water in a graduated cylinder. The metal sank to the bottom, and the water level rose from 15.7 mL to 25.3 mL. What is the identity of the metal? Group of answer choices a. Silver (density = 10.49 g/cm3) b. Aluminum (density = 2.64 g/cm3) c. Lead (density = 11.34 g/cm3) d. Tin (density = 7.31 g/cm3)
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 piece of metal having a density of 19.3 g/mL when dropped into a graduated cylinder containing 50 mL of water the reading was 61.3 mL. When the metal was heated from 25°C to 50°C the heating required 703.34 joules of heat. What is the heat capacity of the metal? O 0.129 J/g-°C O 1.29 J/g-°C 0 0.024 J/g-°C O 0.24 J/g-°C 0 2.40 J/g-°C
(3 points) A 40.0 g gold object is placed in a graduated cylinder containing 53.4 mL of water. What is the new water level in the cylinder? The density of gold is 19.3 g/mL.
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...
A sample of aluminum metal is placed in a graduated cylinder. It is noted that 5.50 mL of water is displaced by the aluminum. The aluminum is then reacted with excess nitric acid to produce aluminum nitrate and hydrogen gas. Given the density for aluminum is 2.702 g/mL, how many grams of aluminum nitrate are produced in the reaction? 2Al(s) + 6HNO3(aq) + 2Al(NO3)3(aq) + 3H2(g)
A sample of iron metal is placed in a graduated cylinder. It is noted that 10.4 mL of water is displaced by the iron. The iron is then reacted with excess hydrochloric acid to produce iron (II) chloride and hydrogen gas. Given the density for iron is 7.86 g/mL, how many grams of iron (II) chloride are produced in the reaction? Fe(s) + 2HCl(aq) - FeCl2(aq) + H2(g)
