How do you make a 1 M solution?
The atomic mass (or weight) of Na is 22.99, the atomic mass of Cl is 35.45, so 22.99 + 35.45 = 58.44.
If you dissolve 58.44g of NaCl in a final volume of 1 liter, you have made a 1M NaCl solution, a 1 molar solution..
What does M solution mean?
Key Points. 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.
What is molar and normal solution?
Molar and normal solutions are used in the chemical analysis of raw materials. A specific amount of chemical (solute) is dissolved to obtain the solution of required concentration (molar or normal solutions).
What does 0.5m mean?
You know that “0.5 M” literally means 0.5 moles per liter.
What is a 5% solution?
For example: Mix 500 mL of water and 25 g of NaCl to make a 5% solution. Remember, if you’re diluting a liquid compound, you must subtract out the volume of liquid being added from the final volume: 500 mL – 25 mL = 475 mL of water.
How can we prepare 0.1 N NaOH in 100 ml?
To make 0.1N NaOH solution = dissolve 40 grams of NaOH in 1L of water. For 100 ml of water = (4/1000) × 100 = 0.4 g of NaOH. Thus, the amount of NaOH required to prepare 100ml of 0.1N NaOH solution is 0.4 g of NaOH.
