Molarity means the number of mol of a substance per 1 litre of substance. Or figure out the number of mol of NaCl ((2.60/(23+35)=0.04) then multiply the 35ml by 28.571428 to get that to litres.. then multiply the number of mol by 28.571428 to get that to the number of mol. Therefore the answer is 1.142857M. See the Related Questions link "How do you prepare a solution of a specific concentration?"

∙ 11y agoMolarity = moles of solute/Liters of solution
2.00 M = 2.60 moles NaCl/X volume
Volume = 2.60/2.00
= 1.30 Liters in volume

What is the molarity of a solution where 4.00 moles of Potassium Chloride is dissolved in 3.00 L of solution?
The molarity of a solution given by the number of moles divided by the volume it contains. Hence, the molarity of KCl is 4.00/3.00 = 1.33 mol/L.
What is the molarity of a solution prepared when 75.0 ml of a 4.00 m kcl solution is diluted to a volume of 0.500 l?
0.6m
An alcoholic iodine solution is prepared by dissolving 4.65 g of iodine crystals in enough alcohol to make a volume of 235 mL Calculate the molarity of iodine in the solution?
molarity = no. of moles of solute/liter of solution no. of moles of I2 = mass in grams/molar mass = 4.65/253.81 = 0.01832 mol M = 0.01832 mol/0.235 L = 0.0780 mol/L
Explain why molality is used for boiling point elevation and feezing point depression calculations and molarity is used for osmotic pressure calculations?
Molality is independent of temperature, so when you are trying to find changes in boiling and freezing points you need something that will stay constant regardless of the change in temperature. Molarity is temperature dependent and also is based on the volume of a solution, both of which are needed to calculate pressure using the ideal gas law, PV=nRT. Osmotic pressure is similar but we substitute the number of moles of the solution and the volume by using the molarity, you cannot do this with molality, since it is dependent on mass, not volume.
A solution is made by dissolving 17.52g of nacl exactly 2000 ml what is the molarity of this solution?
concentration or molarity = number of moles/volume number of moles (n) = mass in grams of nacl/relative atomic mass of nacl n=17.52/(23+35.5) n = 0.2994872 mol volume = 2000/1000 = 2dm^3 molarity = 0.2994872/2 =0.15mol/dm^3
Could you calculate the molarity of a solution you need to know the moles of solute and the?
volume of the solution
How do you calculate molarity of substance?
Molarity (M) = mole of solute (mol)/volume of solution that it is dissolved into (L) Make sure that the volume is converted to L if it isn't already, otherwise you will get wrong answers.
To calculate the molarity of a solution, you need to know the moles of solute and the?
You need to know the moles of solute and the VOLUME of SOLUTION.
How do you calculate moles from molarity?
Number of Moles = concentration * volume (in litres)
What is the effect on the molarity of a solution of adding more solvent to a 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.
How do you calculated the value for molarity?
Molarity= No. of moles of solute/Volume of solution(in litre) or No. of moles of solute*1000/Volume of solution(in ml)
Definition of molarity and its equation?
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
What is the molarity a measure of?
Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.
Why molality is not temperature dependent?
Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.
A solution of NaOH contains 20g of this compound in 2dm3 of this solution . What is molarity of this solution?
This sodium hydroxide solution has a molarity of 0,25.
What is the molarity of a solution containing 15.0g of aspartame dissolved in water and the solution volume is brought to 250.00mL by adding water?
The molarity is o,2.
How do you calculate grams of a compound in a solution?
- measuring the mass of this compound and the volume (or mass) of the solution - by chemical analysis (and determination of the concentration of this compound) If you know the molarity, multiply moles by molecular weight and adjust per the volume you have. If you don't know the molarity, a simple means is to just evaporate the solvent and weigh the remaining compound
