## How do you convert between grams and moles of a specific molecule?

To convert grams to moles, you will need to molar mass of that specific element, molar mass is found my multiplying the number of atoms present in the compound by the relative atomic mass found on the bottom of the element block.

## How do you convert grams to moles?

Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

## How do you convert between grams and moles of a specific molecule quizlet?

Using a calculator, divide the number of grams by the molar mass. The result is the number of moles in your element or compound. For example, imagine you have 2 g of water, or H2O, and you want to convert it to moles. The molecular mass of H2O is 18g/mol.

## How do you convert between molecules and moles?

Converting between molecules and moles is done by either multiplying by or dividing by Avogadro’s number:

1. To go from moles to molecules, multiply the number of moles by 6.02 x 1023.
2. To go from molecules to moles, divide the numbers of molecules by 6.02 x 1023.

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How do you find the mass of a mole quizlet?

Multiply the atomic weight of each element by the number of atoms of the element in the molecule, and add these to calculate the compound molar mass. In the example, the molar mass of Na2SO4 is (23 x 2) + (32 x 1) + (16 x 4) = 142 grams per mole. For example, suppose the mass of your sample of Na2SO4 is 20 g.

## How do we then get from moles to mass quizlet?

1) Given X mole of Element – need grams of Element. 2) Find Molar Mass what 1 mole of Element is – then multiply Molar Mass to X mole of element.

1. Given Mass (A) of Molecule.
2. Add Molar Mass of each element in Molecule.
3. Divide (A) into Molar Mass of combined Elements.

## Are moles and molecules the same?

A mole is the measure of a certain number of atoms. … 1 mole of any element or compound contains an Avogadro number of atoms that is 6.022×1023 atoms. On the other hand, a molecule is a substance that contains the same or the different atoms of elements.

## How do you find moles of atoms in a compound?

To find the number of moles of a compound you have on hand, look up the molecular weight of the compound and divide that number into the weight you have on hand. If you know the number of moles, you can find the weight by multiplying the number of moles by the molecular weight.
