Molarity is defined as moles/liters. So the concentration of your solution (your answer) is 1 M. You have a one molar solution (mol/L).

Molarity is defined as grams of solute dissolved in 1 liter of solution and molality is defined as grams of solute dissolvd in 1Kg of solvent

Within a set volume of solvent (usually water), a concentrated solution will have more solute than a diluted silution. In chemistry, this is called molarity. The more moles of solute you have in solution, the higher the concentration, or molarity of that solution. Molarity is defined as moles solute/liter solvent, and is abbreviated "M".

Molarity is defined as moles solute/liter of solution.Moles of solute = 2.5 moles sucrose Liters of solution = 0.5 liters Molarity (M) = 2.5 moles/0.5 liters = 5 M

Molarity solution is not a term that I have ever heard used. Molarity is always a term used to describe a concentration of solute in a solvent, i.e. of a solution. The closest I've heard to molarity solution is when people ask "what is the solution's molarity".

Molarity of a solution is equal to mol/L.

This cannot be answered as written. Molarity is defined as moles of solute per liter of SOLUTION. There is no way to calculate the volume of the entire solution when given the mass of the solvent. You need to measure the volume of the solution (in litres) after it has been made at room temperature and then just divide.molarity = moles / liters of solution

Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ==========

Molarity of a solution depends upon volume of solution, the change in temperature changes the volume so molarity changes.

a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.

why molarity is preferred over molarity in expressing the concentration of a solution

Molarity (M) is defined as moles of solute/liters of solution. Assuming the final volume is 500 ml (0.5 liters), then M = 1.2 moles/0.5 liters = 2.4 M

Molarity= (number of moles of solute)/(volume of solution in dm3)

Molarity is an indication for concentration.

Sugar does not have measurable molarity. Molarity is used to determine the concentration of a solute in a solution. For example, you could measure the molarity of sugar in a sugar-water solution.

Adding more solvent to a solution decreases the molarity of the solution. This is based on the principle that initial volume times initial molarity must be equivalent to final volume times final molarity.
