## How many moles are in 39.10 g of potassium?

The molar mass of potassium is 39.10 g/mol. Therefore: n moles of potassium atoms will have a mass of (n TIMES 39.10) g. OR: **6.89 moles** of potassium atoms will have a mass of (6.89 TIMES 39.10) g, which is equal to 269 g.

## How many moles are found in 25 grams of potassium?

25122.4 = moles. **2.05 moles** of Potassium Chlorate. There is a 1:1 mole ratio. 1 mole of Potassium Chlorate will produce 1 mole of Potassium Chloride.

## What is 1 mole in grams?

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 mass of 2.5 mole of co2?

2.5 mole of co2 = 2.5 x 4.4 = **11g**.

## 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.

## What name is given to the number of particles in a mole?

**Avogadro’s number** is the number of units in one mole of a substance, or 6.02214076 × 10^{23}. This number is also called the Avogadro constant.
