## 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 many moles are in 5 grams?

How many moles are 5 grams of calcium ? (Atomic mass of calcium =40u). Thus, there are **0.125 mole** in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.

## 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 grams of KCl should be added to 75?

Therefore, **12.57 g** of KCl must be added to 75 gram of water to produce a solution that is 2.25 molal.

## How many grams are in 1 mole of KBR?

Explanation: Now the molar mass of potassium bromide is **119.0⋅g⋅mol−1** .

## What is 1 mole in grams?

Another property of Avogadro’s number is that the mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight **18.015 grams**.

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. **Multiply the given number of moles** (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

## How many grams are in 0.125 moles of KCl?

Thus, add to get the molar mass for KCl , which is **73.551g**/mol .

## How many grams are in 2 moles of NaBr?

1 Expert Answer

We use total molar mass of NaBr to convert from moles of NaBr into grams of NaBr. 22.99+79.90= 102.89 g/mol NaBr. So, there is **226.36 grams** of NaBr in 2.20 moles of NaBr.

## How many grams are in 1 mole of CCl4?

1 mole is equal to 1 moles CCl4, or **153.8227 grams**.

## How much KCl in grams should the chemist use?

Step1: Molarity(M) is defined as number of moles of solute dissolved in one litre (or one cubic decimetre) of solution. = **18.64 g**. Thus, the required mass of KCl is 18.64 g.

## How many grams of KCl are produced?

Find the gram molecular mass of Potassium Chloride. = 74.4 grams / mole. Ernest Z. The reaction will produce **15.3 g** of KCl .
