Aside from a few of the ultra-high-molecular-weight polymers I can't imagine a single molecule that had a mole of anything in it. But since you asked...

1. Figure out how many grams a mole of the compound weighs. Easy one: a mole of water weighs 18 grams - two grams worth of hydrogen, 16 grams of oxygen.

2. Now determine the mass of the sample you have. Our sample has a mass of 990 grams - our sample is a liter of distilled water that we took 10 ml from to make the math easier. 990 grams of water is 55 moles.

3. Multiply the number of moles you have by the number of each atom in the compound. Here we have 110 moles of hydrogen atoms (or 55 moles of H2 molecules) and 55 moles of oxygen atoms (or 27.5 moles of O2 molecules).

How can one determine the empirical formula from moles in a chemical compound?

To determine the empirical formula from moles in a chemical compound, you first need to find the moles of each element present in the compound. Then, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.


How do you work out the number of moles of unknown compound if you are only given the molar mass?

To find the number of moles from molar mass, divide the mass of the compound by its molar mass. The formula is: Moles = Mass (g) / Molar Mass (g/mol). This will give you the number of moles of the unknown compound.


Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?

To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.


How to determine the empirical formula of a compound?

How is the mass compound determined from the number of moles?

Multiply the number of moles times the molar mass of the compound. Moles cancel and you are left with mass in grams.For example: What is the mass of 2.47 moles of sodium chloride, NaCl?Known: The molar mass of NaCl is 58.44g/mol. (Using atomic weights in grams from the periodic table.)Solution:2.47mol NaCl x 58.44g/mol NaCl = 144g NaCl
