How do you prepare 1.5 m NaCl solution mol wt 58.44 g mol?

Since the question asks to make 100 ml not 1 liter we need to make that adjustment. 1.5 moles = 1.5 moles x 58.44 g/mol = 87.66 g. This is the mass needed to make 1 liter (1000 ml). Procedure: weigh out 8.8 g NaCl and place into a 100 ml volumetric flask.

How would you prepare 1.00 liter of a 1.00 molar solution of sodium hydroxide?

so we can said if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution. Weigh 39.9 gm of NaOH pellets & dissolve them in one liter of water what you will be having now is 1M NaOH solution.

How do you make a 0.5 M solution?

To prepare a 0.5 M solution weight out 0.5 moles of glucose. One mole of glucose is 180 grams so 0.5 moles of glucose would be 90 grams (180 g/mole X 0.5 mole = 90 g). Then add water until you have 1 liter of solution (0.5 moles/liter).

What does n m/m mean?

n = m/M n is the amount of substance in moles mol. m is the mass of the substance in grams g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1. Molar masses: These. will be given in.

How do you calculate moles from molarity?

  1. First you must calculate the number of moles in this solution by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
  2. For NaCl the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
