How do I calculate molecular mass?
Find the atomic mass for each element using the mass shown in the Periodic Table or Atomic Weight Table. Multiply the subscript (number of atoms) times that element's atomic mass and add the masses of all the elements in the molecule to obtain the molecular mass.
How many molecules of sucrose are there?
Moles of sucrose=454⋅g342.30⋅g⋅mol−1=1.33⋅mol . Now it is a fact that in a mole of stuff there are 6.022×1023 individual items of stuff……… So 1.33⋅mol×6.022×1023⋅mol−1≅8×1023 individual sucrose molecules.
How many atoms are present in C12H22O11?
Your answer is in your question C12 means 12 carbon atoms, H22 means 22 hydrogen atoms O11 means 11 oxygen atoms. So, the number of atoms in C12H22O11 (sucrose) is equal to “12 (carbons) + 22 (hydrogens) + 11 (oxygens) = 45 atoms!

How do you calculate molecules?
Calculate he number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.
How do you calculate molecules in sucrose?
Multiply the number of moles by Avogadro's number, 6.02 × 1023, to determine the number of molecules in the granule of sugar.
How do I find the mass of carbon?
The mole is defined as a number of particles, 6.022 ´ 1023 particles to be accurate. To calculate the mass of a single atom of carbon, we just need to divide the molar mass of 12.0 g (0,012 kg) by the number of particles per mole (Avogadro's number). Doing so yields 1.99 ´ 10–26 kg as the mass of a carbon atom.
What is the mass of 6.02 x10 23 atoms of carbon?
12.01 grams This means that 6.022×1023 carbon atoms (or molecules) weights 12.01 grams. Read more about the mole here or at hyperphysics.
How many molecules are in 1.5 moles?
Number of molecules in 1.5 moles of ammonia = 1.5 × 6.022 × 1023, Therefore, the number of molecules in 1.5 moles of ammonia is 9.033 × 1023.
What is the mass of 1 carbon?
Average Atomic Mass On the periodic table the mass of carbon is reported as 12.01 amu. This is the average atomic mass of carbon. No single carbon atom has a mass of 12.01 amu, but in a handful of C atoms the average mass of the carbon atoms is 12.01 amu.

Why is a mole 6.022 x10 23?
The MOLE (mol) is a unit of measurement that is the amount of a pure substance containing the same number of chemical units (atoms, molecules etc.) as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 1023).
What is unit of Avogadro no 6.023 x10 * 23?
The Avogadro constant (NA or L) is the proportionality factor that relates the number of constituent particles (usually molecules, atoms or ions) in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined exactly as NA ≡ 6.02214076×1023 mol-1.
