## 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 find 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 particles are in 7.5 moles?

Explanation: And Avogadro’s number , 6.022×1023⋅mol−1 specifies a molar quantity…… And so 7.5⋅mol×6.022×1023⋅mol−1≅**4.5×1024 sulfur atoms** .

## How many moles are in 11g of CO2?

So, 1 mole of CO2 is 44 gm. To find: Number of moles in 11 g of CO2. =**0.25 mole**.

## 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.

## How many grams of KCl would be dissolved in 60g?

As above explanation, we know The correct answer is **15 g**.
