# What Is Meant By 1 M Solution?

## 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.
