First, you need to find the mole of the molecule. A molecule may contain many types of atoms and a different number of each atom.
Second, each mole of the molecule contains 6.02 x 10^23.
Third, solve the formula.
Example: C9H8O4 contains 0.360 grams of aspirin. How many grams does this molecule have?
Mole of aspirin = 9 carbon 8 of hydrogen and 4 of oxygen = 180 grams/1 mole
0.360 grams of aspirin x 1 mole aspirin/180 grams aspirin = 0.360/180 = 0.0020 moles of aspirin.
Second step: Each mole aspirin contains 6.02 x 10^23 molecules.
0.0020 moles aspirin x 6.02 x 10^23 molecules/1 mole aspirin = 1.20 x 10^21 molecules of aspirin.
Answer = 1.20 X 10^21 molecules of aspirin.

∙ 11y agoDepends on the molar mass.
It depends on the molar mass as stated by the previous answer, and of the actual substance. To convert grams to molecules, you would take grams and divide it by the molar mass of that substance.
CONVERSION FACTOR
Grams of substance x 1 mol
/////////////// molar mass substance
FINDING MOLAR MASS
Number of atoms Element A x Atomic Mass Element A (Periodic Table) = amu el. A
Number of atoms Element B x Atomic Mass Element B (Periodic Table) = amu el. B
... etc.
Add up all of the values found above and you have found the molar mass.
Ex. HCl
1 atom Hydrogen x 1.008 = 1.008
1 atom Chlorine x 35.45 = 35.45
Molar Mass = 36.46

Calculate the number of molecules given grams i.e how many molecules are there in 21.6 grams of CH4?
You would multiply the number of grams x Avogadro's number=number of molecules: (21.6g) X (6.022x10^23)= 1.301x10^25 molecules
How do you convert milligrams to 2.8 grams?
1000 milligrams is equal to 1 gram, therefore 2.8 grams is equal to 2800 milligrams. To convert from grams to milligrams multiply by 1000, and to convert milligrams to grams divide by 1000.
What are the steps needed to convert 77.2 grams of methane to molecules of methane. Please wrote them out ( indluding tchart)?
Step1: Find molar mass of methane, CH4. C=12; H=1; 12+1+1+1+1 = 16 g/moleStep2: Convert grams to moles. 77.2 g x 1 mole/16 g = 4.825 moles methaneStep3: Convert moles to molecules using Avogadro's number.4.825 moles x 6.02x10^23 molecules/mole = 2.90x10^24 moleculesUnfortunately, I don't know what a tchart is, so I didn't include it.

Can you convert from molecules to moles?
to convert molecules into moles, simply use the formula n=N/NA where NA is Avogadro's number(6.022E23). This formula can be rearranged so to convert from moles to molecules (N=nNA). to convert from molecules to moles you use the equation n=N/NA where NA is Avogadro's number (6.022E23)

How many molecules in a mass of 3.9mg of C27H46O?
The molecular weight of it is 386.654g/mol. Convert mass to grams (i.e. 0.0039g). divide mass by molec weight to get 1.0083573x10^-5 moles. Multiply this by avagadros number to get the amount of molecules. this gives you 6.072x10^18 molecules.
