Answer: Number of moles of NaCl per liter of solution
Explanation: Molarity can be defined as the number of moles
of solute per liter of solution.
Therefore the molarity of an aqueous solution of NaCl is thus defined as the number of moles of NaCl per liter of solution.
As velocity increases, so does kinetic energy
Answer:
Density of the oil is lesser than that of the water
Explanation:
The density of water is given as 1.0g/cm³.
Salad oil is found to float on water, this implies that the density of this salad oil is lesser than that of the water.
- When the density of a substance is greater than another, it will sink. If the density of the salad oil is greater than that of water, then it will sink and not float.
- Since the oil floats on water, the density of the oil is lesser than that of the water.
Density is the mass per unit volume of a substance.
