In other words it tells you what is the molar mass of the substance with a given formula.
 

1. What is C12H22O11?

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.

2. What does the number 342 g/mol represent?

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.

3. Why is the molar mass of sucrose important?

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.

4. How is the molar mass of sucrose calculated?

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.

5. Is the molar mass of sucrose the same as its molecular weight?

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.
