## 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?

- 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.
- 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.
