Interpretation:
Given problem “How many molecules of H2O are present in 25.4 g of H2O?” is characterized as what has to be chosen from the given options.
Concept Introduction:
Using the
Molar mass of a substance gives a relationship between the number of grams and number of moles of that particular substance.
The Chemical formula subscript also provides relationship between the number of moles of substance to the number of moles of its individual components present in the substance.
All the three above relationship can be put into a single diagram as shown below,

- 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.
