Molarity can be defined as the moles of solute in a liter of solution. The molarity of the salt solution is 
.
<h3>What is the relation between moles and volume?</h3>
The moles are the mass of substance with respect to the molar mass. The moles and volume relationship can be expressed in terms of molarity.
The molarity can be expressed as:
The given solution has,
- Moles of salt =
- The volume of solution =
L.
Substituting the values for molarity as:
The molarity of the solution is . Thus, option C is correct.

Answer:
17.09g/L
Explanation:
Density = total mass of elements/ volume
We need to find the mass of each mixture constituents using their molar mass:
mole = mass/molar mass
For Neon (Ne) which contains 0.650mol;
0.650 = mass/20.18
mass = 0.650 × 20.18
mass = 13.12g
For Krypton (Kr) which contains 0.321mol;
0.321 = mass/83.79
mass = 0.321 × 83.79
mass = 26.89g
For Xenon (Xe) which contains 0.190mol;
0.190 = mass/131.3
mass = 0.190 × 131.3
mass = 24.95g
Total mass = 13.12g + 26.89g + 24.95g = 64.96g
Density = total mass / volume
Density = 64.96g / 3.80L
Density of the mixture = 17.09g/L
