How many sulfur atoms are there in 5. Since 1 molecule of sulphur contains 8 atoms. 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.

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6. Converting between molecules and moles is done by either multiplying by or dividing by Avogadro's number: To go from moles to molecules, multiply the number of moles by 6.

To go from molecules to moles, divide the numbers of molecules by 6. For H2O, there is one atom of oxygen and two atoms of hydrogen. Answer and Explanation: There are Use the molecular formula to find the molar mass; to obtain the number of moles , divide the mass of compound by the molar mass of the compound expressed in grams.

We assume you are converting between grams Hydrogen and mole. You can view more details on each measurement unit: molecular weight of Hydrogen or mol The molecular formula for Hydrogen is H. The SI base unit for amount of substance is the mole.

The answer is This tells you that one mole of sulfur atoms , "S" , has a mass of "32 g". Next, use Avogadro's number to figure out how many "S" atoms you get in 6 moles , knowing that one mole of an element contains exactly 6. So, 6 moles means that you get six time more atoms than you would get in one mole, so you have. The answers are rounded to three sig figs , the number of sig figs you gave for the mass of sulfur.
