The following conditions must be met before a standard calibration curve equation can be used to solve for the concentration of
zzz [600]

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.

Thomas poured 25 mL of 0.60 M HCl into a large bottle. He then added enough water so that the new (diluted) concentration was 0.
Molodets [167]

Answer:

The answer to your question is 150 ml

Explanation:

Data

Volume 1 = 25 ml

Concentration 1 = 0.6 M

Volume 2 = ?

Concentration 2 = 0.1 M

Formula

            Volume 1 x Concentration 1 = Volume 2 x Concentration 2

Solve for Volume 2

             Volume 2 = (Volume 1 x Concentration 1)/Concentration 2

Substitution

             Volume 2 = (25 x 0.6) / 0.1

Simplification

            Volume 2 = 15 / 0.1

Result

            Volume 2 = 150 ml

There are 115 protons in the element 115 and due to the large number of protons, the element does not exist in nature.

Also, the element can not be isolated in nature that is IUPAC had to require an independent confirmation of the element.

<h3>What is element 115?</h3>

We know that the periodic table is an arrangement of the atoms in order of increasing atomic number. We know that the larger the atomic number of the element, the less likely that the element would be stable in nature. The element that have been named 115 is called Moscovium and was discovered in Moscow as a product of a radioactive experiment. The number of protons in element 115 is 115 protons

Generally, the element number 115 does not exist in nature because if the proton number in an element exceeds 82, the repulsion between the protons would make it almost impossible for the nucleus to be a stable nucleus.

The reason why IUPAC had to request an independent confirmation of the element is because it does not exist in nature.
