Table sodium is 22.99 grams per mole. PlusMoreSo to find the molar mass of nacl we go to the periodic. Table sodium is 22.99 grams per mole. Plus chlorine 35.45 grams per mole. We add those up and we get 58.44. And the units are grams per mole.
How many grams of NaCl are required to make 250.0 mL of a 3.000 M?
Make 250 mL of a 0.30 M NaCl solution. To make the solution we need to calculate the amount of NaCl to dissolve to make 250 mL of solution. The solution is made by adding 4.38 g NaCl to a 250-mL volumetric flask.
What is the molarity of a solution containing 0.32 moles of NaCl in 3.4 liters?
0.094 M NaCl Calculating Molarity from Moles and Volume To get the molarity we need to divide the number of moles of NaCl by the volume of the solution. In this case that is 0.32 moles NaCl divided by 3.4 L, and that gives 0.094 M NaCl.
How many moles of NaCl are present in 600.0 ml of 1.55 M NaCl solution?
The answer is 0.930 moles of NaCl.
How do I calculate molarity?
As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.
How do you calculate the molarity of a solution?
The most common way to express solution concentration is molarity (M), which is defined as the amount of solute in moles divided by the volume of solution in liters: M = moles of solute/liters of solution.
How do I calculate moles?
Number Of Moles Formula
- The formula for the number of moles formula is expressed as.
- Given.
- Number of moles formula is.
- Number of moles = Mass of substance / Mass of one mole.

How do you calculate moles per Litre?
1 liter of water weighs 1000 g, and, as molarity is the number of moles per liter; finding the molarity of water is the same as finding the number of moles of water in 1000 g. We therefore divide the weight by the molar mass to get moles, 1000 / 18.02 = 55.5 M.
How would you prepare 250 mL of a 0.10 M NaCl solution?
Answer and Explanation: The correct answer is d) Dissolve 1.46 g of NaCl in 50 mL of H2O H 2 O and dilute to 250 mL.
