Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​
marissa [1.9K]

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M
