The molality of this solution is 1,905; to calculate the molarity you need the density of the solution.
The molarity of a solution containing 7,0 moles of solute in 523 mL of solution is 4.
Molarity = moles of solute/liters of solution Molarity = 7 moles solute/2 Liters solution = 3.5 M ======
This molarity is 2,33.
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
The molarity is 7 mol/L.
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".
The molarity is 0,5 M.
Molarity is number of moles in solute. So molarity of this is 0.5mol-1.
The molarity is a form of expression for the concentration; the molarity of a solution is the number of moles of solute in the solvent. The number of moles is the ratio between the mass of the solute in the solution and and its molar mass.
This solution is impossible.
Molarity = moles of solute/Liters of solution so, 959 milliliters = 0.959 Liters Molarity = 7.0 moles of solute/0.959 Liters = 7.3 M solute ===========
It depends what the solute is. There is no way to determine the molarity without knowing that piece of information.
Molarity = moles of solute/Liters of solution ( 5000 ml = 5 Liters ) Molarity = 90 moles solute/5 Liters = 18 M --------------------the most concentrated possible
moles of solute over kg of solvent
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
It depends highly on the compound to be dissolved and the solvent. Molarity is measured my moles per litre, and if you don't know the molar mass of the compound, you can't work out the molarity.
Molarity (M) is moles of solute per liters of solution. In contrast, molality (m) is moles of solute per kilograms of solvent.
The number of mL is not mentioned.
Concentration relates the amount of solute to the amount of solvent. For instance, in a salt water solution, salt is the solute and water is the solvent. A way to measure the concentration of a chemical would be molarity or M. The molarity stands for the moles of solute in the liters of solvent.
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 = moles of solute/Liters of solution ( 500.0 ml = 0.5 Liters ) Molarity = 0.75 moles/0.5 Liters = 1.5 M
Molarity = moles of solute/Liters of solution ( 500.0 ml =0.500 Liters ) Molarity = 0.75 moles/0.500 Liters = 1.5 M ----------
The molarity is 0,125 M.
in molarity we dissolved no of moles of solute in 1 dm3 volume of its solution but in molality we dissolved no of moles of solute in 1000 gram or 1 kg of solvent in molarity we don't know the exact amount of solvent quantity but in mplality we know the exact volume of solvent ( water)
Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ==========
