## Why do we use moles in chemistry quizlet?

is used to describe the mass of an atom expressed.

## Why is the mole used to measure the atom quizlet?

A large counting unit like the mole is used to count atoms because atoms are too small to count individually. We use the mole to count atoms and molecules because otherwise, we would have to write out very large numbers to show how many atoms were in a certain amount of a substance. Moles are like donuts.

## What is the importance of a mole?

The mole provides a link between an easily measured macroscopic property, bulk mass, and an extremely important fundamental property, number of atoms, molecules, and so forth.

## Why do chemists work with moles instead of individual atoms?

Why do chemists work with moles instead of individual atoms? A mole is a collection of atoms that is large enough to measure. A single atom is too small to measure directly with a balance. … Because the molar mass of oxygen= 16 g/mol, the mass of 1 mol of 6.022 x 10^23, oxygen atom’s is 16.00 g.

## What is a chemistry mole quizlet?

The mole is the amount of substance that contains as many particles (molecules, ions or atoms) as there are in 12g of carbon. This number has been found to be 6.02 x 10^23. Molar Mass (M) Numerically equal to the relative molecular mass of each element in a molecule.

## Why do you think chemists prefer using the mole Why don’t they just count each particle?

Why don’t they just count each particle? Chemists prefer using the mole over counting each particle because one particle is way to small to count by it self, but using the mole, 6.02×10^23, lets them measure a lot more accurately and quicker.

## What is a mole What is it used for and why quizlet?

a Mole is the SI unit of measurement used to measure the number of things, usually atoms or molecules.

## What is the mole used for quizlet?

The mole is a unit for counting 6.02 1023 representative particles. The dozen is used to count 12 items.

## Why is a mole a better unit than a PCU?

Reasons for moles: You can easily approximate the number of atoms from the mass of a sample because the mass number of an isotope approximately equals the mass of 1 mole of atoms in grams. It’s a historical convention that would be too expensive or uncomfortable to change now.
