Write two conversion factors for each of the following. a. a 16% (by mass) salt solution
b. a density of 1.25 g/mL
c. a speed of 25 m/s

Answer//the law of conservation of mass.;

Remember that rust prevented by placing a sacrificial electrode in electrical contact with the iron. the sacrificial electrode must be composed of a metal that  oxidizes  more easily than iron (that is, it must be below iron in table 18.1).

Ican't see the chart but the density of both nickel and cobalt is 8.90 g/cm3, so it would be one of those.
