2.0 mol NaCl / 2.0 Litre = 2.0/2.0 = 1.0 mol/L = 1.0M NaCl
80g of NaOH dissolved in 250ml. of water find the molarity of this solution ?
The Molarity of the solution is .901
what is the molarity of a solution prepared by dissolving 36.0g of NaOH in enough water to make 1.50 liter of solution?
Molarity = moles of solute/Liters of solution Molarity = 10 moles salt/20 Liters solution = 0.50 M salt solution ----------------------------
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
Molarity = Moles/Unit VolumeSo here Molarity = (0.0255) / (10-2) = 2.55 M
The moLaRity of this solution ie 2 mol/L or 2M KI (it is a 'two molair potassium iodide' solution)
The molarity of KNO3 is 0,058.
The molarity of a solution made by dissolving 23,4 g of sodium sulphate in enough water to make up a 125 mL solution is 1,318.
Because you have 6.68 moles of Li2SO4 and 2.500 liters of water, the overall molarity of your solution is 2.67 M.
This depends on the mass of sodium chloride dissolved in a known volume of water.
The molarity is 0.001255. Should you really be asking an AP Chem question on Wiki Answers, anyways?
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)
This solution is 2 molar (2 mol/L).
Concentration of a solution is recorded in molarity (M). Molarity is the moles of solute divided my liters of solution. So to find the concentration of a solution, calculate the number of moles of the solute (the chemical being dissolved) and measure the number of liters of the solution (the water), then divide them.
Need to know the mass of BaCl2 in order to calculate molarity.
Molarity is per litre. Therefore 200x5 is a litre. so 5x5 is 25. The answer is 25 molar.
This molarity is 3 M.
The molarity is 0,388.
Molarity (concentration ) = moles of solute/Liters of solution 250.0 ml = 0.250 liters 2.431 grams H2C2O4 * 2H2O ( 1mole cpd/ 126.068 grams) = 0.01928 moles H2C2O4 * 2H2O Molarity = 0.01928 moles cpd/0.250 liters = 0.07712 Molarity
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.
20.2 g of CuCl2 = .1502 mol CuCl2 M=mol/L M=.1502 mol/L
NaF has an atomic mass of 42, therefore if you dissolve 42 grams (1 mole) of it in 2 liters of water you get a molarity of 0.5 moles/Liter.
