91.4 grams mass of KCl is required.
Concentration = moles/Volume
2.45M=mol/0.5L
2.45M⋅0.5L=mol
mol=1.225
Convert no. of moles to grams using the atomic mass of K + Cl
1.225mol⋅(39.1+35.5)/gmol
1.225mol⋅74.6g
mol=1.225⋅74.6g = 91.4g
What is Concentration?
- The formula for determining concentration from moles and volume is pretty straightforward. Simply divide the volume of solution by the moles of solute.
- The number of moles of a component divided by the sum of the moles in the solution is what is known as a mole fraction, which is a unit of concentration.
- Mole fraction is a unit-free expression because it represents a ratio.
