Sucrose is a compound, not an element and so does not have an atomic number. It is composed of carbon, hydrogen, and oxygen which have the atomic numbers 6, 1, and 8 respectively.
The formula for sucrose is C11H22O11. To figure this out, you need to list the elements in the compound along with the amount of times it is in the compound and the atomic masses of the elements, like so... Carbon 11 12 132 Hydrogen 22 1 22 Oxygen 11 16 176 Add the right column all up and you get 330. So, to reiterate, sucrose has a molar mass of 330 to the nearest gram.
Atomic mass
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
Since magnesium and helium do not form elemental molecules, a mole of these elements is the same as a gram atomic mass, which is 24.305 for magnesium and 4.00260 for helium. The gram molecular mass for sucrose is 342.30. Therefore, the mass of: A. 3 moles of magnesium is 72.915 grams; B 1 mole of sucrose (C12H22O11) is 342.30 grams; and C. 10 moles of helium is 40.0260 grams. The largest of these is obviously the single mole of sucrose.
Sucrose is a compound, not an element and so does not have an atomic number. It is composed of carbon, hydrogen, and oxygen which have the atomic numbers 6, 1, and 8 respectively.
For this you need the atomic (molecular) mass of C12H22O11. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. C12H22O11= 342 grams.105 moles C12H22O11 × (342 grams)= 35.9 grams C12H22O11
To calculate the number of moles in 342g of sucrose, divide the given mass by the molar mass of sucrose. The molar mass of sucrose (C12H22O11) is approximately 342.3 g/mol. Therefore, 342g of sucrose is equal to 1 mole.
The mass percentage of carbon in sucrose can be calculated by dividing the mass of carbon by the total mass of sucrose and then multiplying by 100. In this case, the mass percentage of carbon in sucrose would be (8.4 g / 20.0 g) x 100 = 42%.

To calculate the number of moles of sucrose in 200 grams, you need to divide the given mass by the molar mass of sucrose. The molar mass of sucrose is approximately 342 grams/mol. Therefore, 200 grams of sucrose is equal to 0.585 moles.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
