Carbon monoxide, CO, and hydrogenreact according to the equation below. 3 C O ( g ) + 7 H 2 ( g ) → C 3 H 8 ( g ) + 3 H 2 O ( g ) What volume ofwhich reactant gas remains if 12.0 L CO(g) and 25.0 L H 2 (g) are allowed to react? Assume that the volumes ofboth gases aremeasured at the same temperature and pressure.

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.
a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2
- Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)?
- Which units express concentrations in numbers with easily expressed magnitudes?
- Suppose you have an analyte for which you don't know the molar…
