What is the concentration of a solution if 2.0 moles of sodium chloride is dissolved in 0.50 liter of water?

Answer 1

To calculate the concentration of the solution, we need to use the formula:

Concentration (molarity) = moles of solute / liters of solution

Given that 2.0 moles of sodium chloride is dissolved in 0.50 liters of water, we can plug in the values:

Concentration = 2.0 moles / 0.50 L
Concentration = 4.0 M

Therefore, the concentration of the solution is 4.0 M (moles per liter).
