What is the molarity of 2.3 mol of Kl dissolved in 0.5 L of water

Chemistry
1 answer:
Nastasia [14]3 years ago
4 0

Answer:

4.6\,\,moL\,\,L^{-1}

Explanation:

Molarity refers to a measure of concentration.

Molarity = moles of solute/Litres of solution

Molarity refers to number of moles of solute present in this solution.

In order to find a solution's molarity, use value for the number of moles of solute  and the total volume of the solution expressed in liters

As molarity of 2.3 mol of Kl is dissolved in 0.5 L of water,

Molarity = \frac{2.3}{0.5} =4.6\,\,moL\,\,L^{-1}

Komok [63]

Answer:

Option (D)

Explanation:

Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.

It is highly essential. Every day, a large quantity of oil is being consumed. According to the researches done in the year 2015, it has been observed that the average global consumption of oil was 95 million barrels each day.

It has a high demand, and so it is being regularly used, and it has also been predicted that the present global oil reserves would be highly exhausted within the next 50 years.

Thus, the correct answer is option (D).
