Use the law of constant composition to complete the table summarizing the amounts of iron and chlorine produced upon the decomposition of several samples of iron (III) chloride Remember that, according to the law of constant composition, the ratio of the masses of the two elements
must the same in samples.
Mass FeCl3 | Mass Fe | Mass Cl | |
Sample A | 3.785 g | 1.302 g | 2.483 g |
Sample B | 2.175 g | _______ | ______ |
Sample c | ______ | 2.012 g | _______ |
Sample D | ______ | _______ | 2.329 |

- Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4- 1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer.
