- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How do you calculate 1 mole of NaCl?

If you had the compound sodium chloride (NaCl), you would **add the mass of 1 mol of sodium and 1 mol of chlorine**. This would give you the mass of 1 mol of sodium chloride which would be about 58.443 g.

## How do you calculate moles from molarity?

To calculate the number of moles in a solution given the molarity, we **multiply the molarity by total volume of the solution in liters**.

## How do you find 1 mole of Na?

How many atoms are in a 3.5 g sample of sodium (Na)? In this example, multiply the grams of Na by the conversion factor 1 **mol Na/ 22.98 g Na**, with 22.98g being the molar mass of one mole of Na, which then allows cancelation of grams, leaving moles of Na.

## How many moles are in HCl?

Using periodic table you can find molar mass of HCl, which is 36.458 g/mol. This means 1 mol of HCl is 36.458 grams. So 20 g of HCl is **0.548 mol**.
