Answer:
I think it's pf5or I don't know how to make the answer
Explanation:
,
Answer:
The same instrument must be used to measure the unknown solution as was used to measure the known (standard) solutions that were used to create the calibration curve.
The analyte in the unknown solution must be the same analyte (or type of analyte) that is present in the known (standard) solutions that were used to create the calibration curve.
Domain and range restrictions must be observed.
Explanation:
Calibration curves are tools necessary in understanding the instrumental response for any analyte.
A calibration curve is obtained by preparing a set of standard solutions with known concentrations of the analyte. The instrument response for each concentration is measured and plotted against the concentration of the standard solution. The linear portion of this plot may be used to determine the unknown concentration of a sample of the analyte.
The equation of the best-fit line is used to determine the concentration of the unknown sample.
1) It was Avogadro (option E).
The full name is Amadeo Avogadro. He was a famous Italian scientific. He formulated the Law that states that same volume of gases at same temperature and pressure corresponds same number of particles.
2) Cathode rays are electrons and have the largest charge mass / ratio of fundamental particles found in the atom (option E)
For example, electrons have the same charge magnitude than protons, but the mass of the electrons is a small fraction of the mass of the protons. (1/1840)
