C12H22O11 = 342 g/mol What does it mean?
Thank you very much.phyzguy said:It means that 1 mole of C12H22O11 molecules = 6.02*10^23 C12H22O11 molecules will weigh 342 grams.
C12H22O11 is the chemical formula for sucrose, commonly known as table sugar. It is a compound made up of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.
The number 342 g/mol is the molar mass of sucrose. This means that one mole of sucrose, which is equivalent to 6.02 x 10^23 molecules, has a mass of 342 grams.
The molar mass of a substance is important because it allows us to convert between the mass of a substance and the number of moles present. This is useful in chemistry calculations and experiments.
The molar mass of a compound is calculated by adding the atomic masses of each element present in the compound. In the case of sucrose, we would add the atomic masses of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms to get a total molar mass of 342 g/mol.
Yes, the molar mass and molecular weight of a substance are often used interchangeably. Both refer to the mass of one mole of a substance in grams.
