There are a number of ways to express concentration of a solution. This includes molarity and molality. Molarity is expressed as the number of moles of solute per volume of the solution while molality is expressed as the number of moles solute per mass of solution. Calculation is as follows:
(2 mol NaCl / L solution) ( 1 cm^3 / 1.35 g) ( 1000 L / 1 cm^3) (1000 g /kg) = 1.5 x 10^6 mol / kg solution
I don't understand, so I will say what I think you mean, The direction you want is North.
The correct response is C. Chlorine forms 1 covalent bond while Oxygen forms 2 covalent bonds.
The answer is Velocity and potential energy. Kinetic energy is the total energy of a system or an object in motion and requires movement.
