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.
The atomic mass unit is used to express the measure of the atomic mass.
The atomic mass of magnesium is approximately 24.305 atomic mass units (amu).
The percent, by weight of 17g of sucrose in 188g of water is calculated as follows Mass of Sucrose / Total Mass of Solution *100% = 17 / (188 + 17) * 100 = 8.29%
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
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.
What mass of sucrose C12H22O11 is needed to make 500 ...
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.

The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The atomic mass unit is used to express the measure of the atomic mass.
Cobalt is an atomic mass of 58.93 atomic mass units
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Atomic no.=no. of protons Atomic Mass=no. of protons+no. of neutrons Hence, atomic mass is greater
