Calculate the concentration when 2 mol of table salt is dissolved in 250 cm³ of water.

To calculate the concentration of the solution, we first need to convert the volume of water from cm³ to liters:

250 cm³ = 250/1000 = 0.25 L

Next, we calculate the concentration using the formula:

Concentration = moles of solute / volume of solution in liters

Given that 2 mol of table salt is dissolved in 0.25 L of water:

Concentration = 2 mol / 0.25 L = 8 mol/L

Therefore, the concentration of the solution is 8 mol/L.

Step 1: Convert the volume of water to liters

250 cm³ = 0.25 L

Step 2: Calculate the molarity (concentration)

Molarity (M) = moles of solute / liters of solution

M = 2 mol / 0.25 L
= 8 M

Therefore, the concentration of the table salt solution is 8 M.
