Question

4 moles of solid nacl are added to 4 l water, where they dissociate completely. what's the total molar concentration of solutes in the resulting solution?

Answer 1

The total molar concentration of solutes in the resulting solution is 1 mol/L.

Step-by-step explanation:

The total molar concentration of solutes in the resulting solution can be calculated by first determining the number of moles of NaCl that dissociate in the water. Since 4 moles of solid NaCl are added to 4 L of water and they dissociate completely, the resulting solution will contain 4 moles of NaCl. The total volume of the resulting solution is 4 L.

To calculate the molar concentration of NaCl, divide the number of moles by the volume of the solution in liters:

Molar concentration = Number of moles / Volume of solution

Molar concentration = 4 moles / 4 L = 1 mol/L

Answer 2

Answer:
Molarity = 1 mol.L⁻¹

Solution:
Molar concentration (Molarity) is given as,

Molarity = Moles / Volume of Solution ------ (1)

Data Given;

Moles = 4 mol

Volume = 4 L

Putting Data in Eq. 1,

Molarity = 4 mol ÷ 4 L

Molarity = 1 mol.L⁻¹
