The number of atoms is 28,099.10e23.
Carbohydrates do not contain "g" atoms. Thus we can not answer your question.
593 g H2O x 1 mol/18 g x 2 mole H/mole H2O x6.02x10^23 H atoms/mole H = 4x10^25 atoms of H
78.96 g of selenium will have 6.023 x 1023 atoms. So, 30.4 g of selenium will have 2.32 x 1023 atoms.
5 g of sulfur contain 0,94.10e23 atoms.
1.6 g C x 1 mol C/12 g x 6.02x10^23 atoms/mol = 8.1x10^22 atoms
85.9 (g C) = 85.9 (g C) / 12.00 (g/mol C) = 7.158 (mol C)7.158 (mol C)*[6.022*1023 (atoms/mol C)] = 4.31*1024 C-atoms
169 g C x 1 mole C/12.011 g x 6.02x10^23 atoms/mole = 8.47x10^24 atoms
The number of atoms is 28,099.10e23.
Since 12 g C is 1.0 mole C there are 6.02*10+23 atoms in (each) mole; that's the definition of a mole
Carbohydrates do not contain "g" atoms. Thus we can not answer your question.
Divide mass (g) by molar mass (g/mol) : 30 g C2H2 = 30/26 g 35 g H2O = 35/18 g
1 mole of carbon (or 12 g) has 6 x 1023 atoms. So, 3 moles of carbon (or 36 g) has 18 x 1023 atoms
One mole of any element contains 6.02 x 1023 atoms. So 1mole of carbon = 6.02x1023 atoms. 0.8mole of carbon = 0.8 x 6.02x1023 0.8 mole of carbon = 4.816 x 1023
Atomic mass of carbon: 12.0 grams1.90 grams × (6.02 × 1023 atoms) / (12.0 grams) = 9.53 × 1022 atoms C
The number of atoms of lead is 6,68.10e23.
divide by the atomic mass and times it by advogadro's number.
