A government laboratory wants to determine whether water in a certain city has any traces of fluoride and whether the concentrat
nexus9112 [7]

<u>Answer:</u> The given sample of water is not safe for drinking.

<u>Explanation:</u>

We are given:

Concentration of fluorine in water recommended = 4.00 ppm

ppm is the amount of solute (in milligrams) present in kilogram of a solvent. It is also known as parts-per million.

To calculate the ppm of fluorine in water, we use the equation:

\text{ppm}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 10^6

Both the masses are in grams.

We are given:

Mass of fluorine = 0.152mg=0.152\times 10^{-3}g    (Conversion factor:  1 g = 1000 mg)

Mass of water = 5.00 g

Putting values in above equation, we get:

\text{ppm of fluorine in water}=\frac{0.152\times 10^{-3}}{5}\times 10^6\\\\\text{ppm of fluorine in water}=30.4

As, the calculated concentration is greater than the recommended concentration. So, the given sample of water is not safe for drinking.

Hence, the given sample of water is not safe for drinking.

laila [671]

The  experimental value of Avogadro's number will be ±0.050.

<h3>What is the degree of accuracy?</h3>

The degree of accuracy refers to the extent to which a measurement is correct. Now we know that the measurement obtained by an instrument is as correct as its degree of accuracy.

Hence, given that the margin of error is about 0.050, the  experimental value of Avogadro's number will be ±0.050.
