You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles

eg for water, 36 grams / 18 atomic units = 2 moles

How do you convert atoms to grams with Avogadro's number?

divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.


How to convert grams to atoms?

To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.


How many atoms are there in 55.8 grams of Fe?

Avogadros number (approximately). The atomic weight of iron is 55.845. Avogadros number , the number of atoms in a mole of an element, or the number of molecules in a mole of a compound is 6.023 X 1023


How can you convert from molecules to grams?

Multiply the number of moles by the molecular weight.


What number would you use to convert moles of CH4 to grams of CH4?

To convert moles of CH4 (methane) to grams, you would use the molar mass of CH4, which is approximately 16.04 g/mol. Multiply the number of moles of CH4 by this molar mass to obtain the mass in grams. The formula is: grams of CH4 = moles of CH4 × 16.04 g/mol.


Convert the number of grams in 7.4 moles of aluminum phosphate?

The answer is 902,45 g.


Convert grams to moles?

To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.


What values represents the number of molecules of CH3CL in 101 grams of the substance?

To find the number of molecules of CH3Cl in 101 grams of the substance, you would first convert 101 grams of CH3Cl to moles using its molar mass. Once you have the moles of CH3Cl, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.


How do you convert 90 grams of NaCl to moles?

The answer is 1,54 moles.


How many grams in 5.0x1022 molecules of nitrogen monoxide?

To find the number of grams in 5.0x10^22 molecules of nitrogen monoxide (NO), you need to convert the number of molecules to moles and then from moles to grams. First, calculate the number of moles by dividing the number of molecules by Avogadro's number (6.022x10^23 molecules/mol). Then, use the molar mass of NO (30.01 g/mol) to convert moles to grams.


Which mathematical relationship should you use to convert moles of a substance into grams?

You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.


How do you use avogadros number to convert to molecules?

Avogadro's number, approximately (6.022 \times 10^{23}), is used to convert moles of a substance to the number of molecules. To perform the conversion, you multiply the number of moles by Avogadro's number. For example, if you have 2 moles of a substance, the number of molecules would be (2 \times 6.022 \times 10^{23}) molecules. This calculation allows you to relate macroscopic quantities of material to the microscopic scale of atoms and molecules.
