# Use the measurements in the table to determine which unidentified metal has the highest density. metal volume mass a 10.5 cm3 122 g b 14.2 cm3 132 g c 16.1 cm3 115 g d 12.7 cm3 126 g

Answer from: ladybugperez05

Metal A has the highest density.

Explanation:

Density is defined as mass present in unit volume of the substance.

Density of metal A

Mass of metal = 122 g

Volume of metal =

Density of metal B

Mass of metal = 132 g

Volume of metal =

Density of metal C

Mass of metal = 115 g

Volume of metal =

Density of metal D

Mass of metal = 126 g

Volume of metal =

Metal A has the highest density.

Answer from: rosier2230

ANSWER: A

EXPLANATION:

THE FORMULA FOR DENSITY IS MASS DIVIDED BY VOLUME.

D= M/V

So divide the mass by the volume.

For A, 122 divided by 10.5 is 11.62

For B, 132 divided by 14.2 is 9.295

For C, 115 divided by 16.1 is 7.143

For D, 126 divided by 12.7 is 9.921

A IS THE ANSWER BECAUSE ITS THE LARGEST AMOUNG THE OTHERS.

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
