<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:
Both the masses are in grams.
We are given:
Mass of fluorine = 
(Conversion factor: 1 g = 1000 mg)
Mass of water = 5.00 g
Putting values in above equation, we get:
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.
To trigger a drug-dog alert, the
necessary threshold level would be around 1 to 10 micrograms of methyl
benzoate.
In the 1999 Furton study, it was
stated that it would take 500 milligrams of cocaine in order to emit 1 to 10
micrograms of Methyl Benzoate.
A colorless liquid that is poorly soluble in water is one of
the properties of <span>methyl benzoate.</span>
Answer:
Unless they chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each individual gas in a mixture exerts the same pressure that it would exert if it were present alone in the container . The pressure exerted by each individual gas in a mixture is called its partial pressure.
Explanation:
3/5 times 5/3x = 8*3/5. X=24/5 simplified would be x= 4.8 L.
