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 do you find the number of carbon moles in cholesterol c27h46o?
The number of atoms of an element in a molecule is the number subscript immediately following the element symbol in the formula for the molecule. The number of moles of anything in a compound depends on the amount of the compound, which is not stated.
What does number before the compound represent?
In a chemical equation, the number before the compound is the coefficient and indicates the number of moles or molecules or atoms of that particular substance.
How do you work out the number of moles of unknown compound if you are only given the molar mass?
The molar mass of any compound contain a number of molecules equal to the number of Avogadro:6,022 140 857(74).10e+23.

How do you convert from moles of one material to another?
Each compound has a specific molar mass; no conversion.
0.871 moles is how many grams?
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
How many moles in NaCHO3?
A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
What is the number of apples in 0.25 moles of apples?
The question does not contain enough information. The equation is number of moles = mass (of compound) / molecular mass of compound. You do not know the weight of an apple (cannot get one specific figure for this), nor does an apple have a molecular weight
Formula for moles?
number of moles = mass of the material/molar mass
