Low concentration replicate samples of Cd-EDTA gave the following counts in a mass spectral measurement: 195.9, 149.6, 159.3, 174.3, 143.3, 212.7, 164.3, 168.9, 158.3, 175.9. Ten measurements of a blank had a mean of 36.9 counts. A sample containing 2.00 ?M Cd-EDTA gave 1611 counts. Estimate the signal and concentration detection limits for Cd-EDTA.

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
