Concept explainers
Interpretation:
The effect on density of gas particle in cylinder needs to be explained.
Concept introduction:
Density of gas is directly proportional to mass of gas and inversely proportional to its volume.
Answer to Problem 40A
Density of gas decreases because of gas particles. It occupy more volume per unit mass.
Explanation of Solution
From Piston A to Piston B, volume increases but density decreases at constant molar mass. It can be defined by given formula.
Thus, density and volume are inversely proportional to each other. If volume increases, density deceases keeping mass constant.
Density depends upon mass and volume of gas.

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.
