a water sample is found to have a cl- content of 100ppm as nacl what is the concentration of chloride in moles per liter
ladessa [460]

Answer:

The concentration of chloride ion is 2.82\times10^{-3}\;mol/L

Explanation:

We know that 1 ppm is equal to 1 mg/L.

So, the Cl^- content 100 ppm suggests the presence of 100 mg of Cl^- in 1 L of solution.

The molar mass of Cl^- is equal to the molar mass of Cl atom as the mass of the excess electron in Cl^- is negligible as compared to the mass of Cl atom.

So, the molar mass of Cl^- is 35.453 g/mol.

Number of moles = (Mass)/(Molar mass)

Hence, the number of moles (N) of Cl^- present in 100 mg (0.100 g) of Cl^- is calculated as shown below:

N=\frac{0.100\;g}{35.453\;g/mol}=2.82\times 10^{-3}\;mol

So, there is 2.82\times10^{-3}\;mol of Cl^- present in 1 L of solution.

What happens to the area of the world off the coast of Peru
joja [24]

Answer:The Peruvian west coast bordering the Pacific Ocean is a long desert strip that stretches from the departments of Tumbes in the north bordering Ecuador, to Tacna in the south bordering Chile for a total length of 1,555 miles or 2,500 km. The average temperature from December to April is 25 to 28C or 53 to 59F and the average temperature from May to November is 12 to 15C or 53 to 59F.

The coast covers about 10% of the territory but is home to more than 50% of the population. Large cities such as Lima, the capital, Trujillo, Chiclayo and Tacna are located in the coast. Cities along the coast are the center of economic activity attracting people from the interior of the country looking for economic prosperity.
