Grams per liter in the solution give the density of the solution. The density of the solution is 27.4 g/L. Thus, option d is correct.
Density is the ratio of the mass in gms to the volume of the solution in liters.
Given,
Mass of potassium chloride = 8.210 gms
Volume of solution = 0.300 L
Density is calculated as:
ρ = mass ÷ volume
= 8.210 ÷ 0.300
= 27.36 g/L
Therefore, the density of the solution is 27.4 g/L.
