## How many moles are in KCl?

One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5. Add together for the gram-molecular mass of 74.6). If you took 74.6 grams of KCl and diluted this to one liter with water, you would have a 1.00 M KCl solution.

## How do you calculate moles of KCl?

Multiply the number of atoms for each chemical multiplied by the atomic mass. Add up the results from multiplying the numbers to obtain the molar mass for the compound. For example for KCl, (1 atom X 39.0983 Potassium) + (1 atom X 35.453 Chlorine) = (74.5513 g/mol) which is the molar mass for KCl.

## How many moles of KCl are there in 35.5 g?

Since 1 mole of KCl contains 1 mole of K (39.1g) and 1 mole of Cl (35.5g), the molar mass of KCl is 74 . 6 g/mol.

25122.4 = moles.

## How do you make 3 molar KCl?

To make 125 mL of 3M KCl

1. Using digital scale, place 27.96 g KCl powder into weigh boat.
2. In 150 mL flask, mix 27.96 g KCl with 100 mL H2O.
3. Put flask on hotplate/stirrer with stirbar until dissolved.
4. Add H2O to bring volume to 125 mL.
