You will have a 500ml solution of salt water. from this you will take 10.0ml and place it on a balance. you find that the 10.0ml solution has a mass of 10.7 g. what is the density of the 500ml of salt water solution in g/ml?

Given data:

Volume of solution: 500 ml

Mass of 10 ml solution: 10.7 g

Density of whole solution: ?

Mass of 500 ml solution : 10.7/10 * 500 =  535 g

Density = Mass/ volume

Putting values in formula :

D = 535/500 = 1.07 g/ml

                                         Hence    Density = 1.07 g/ml

the objects have the same charge is correct.
