Mass of solid = 16g
Molecular mass of sulphur S8 = 256 amu
no of moles=mass of substance/molecular mass
=16/256
=1/16
no of moles=no of particles/avogadro constant
1/16=N/6.022 x 10^23
=3.76 x 10^22
1.6*avagardo constant Avagardo constant=6.022*10^23
72 grams SO2 (1 mole SO2/64.07 grams)(6.022 X 1023/1 mole SO2) = 6.8 X 1023 molecules of sulfur dioxide ============================
The formula for sulfur trioxide is SO3. The molecular weight is 80.06. The atomic weight of sulfur is 32.06. Therefore, the fraction by weight of sulfur in sulfur trioxide is 32.06/80.06 is 0.4004, to the justified number of significant digits, so that 9.96 grams of sulfur trioxide contains 3.988 grams of sulfur. The number of atoms present in 3.988 grams of sulfur therefore is Avogadro's Number X (3.988/80.06) or 3.000 X 1021 atoms, to the justified number of significant digits. (Note: A depressed final digit in a decimal means that the digit may not be significant.)
Because Atomicity is the number of atoms present in that molecule.
Four moles of sulfur dioxide would consist of how many molecules?
There are s8 sulfur molecules. It shows 0 oxidation number.
1.6*avagardo constant Avagardo constant=6.022*10^23
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
Oxygen & Nitrogen, followed distantly by sulfur.
hydrogen, carbon, nitrogen, oxygen, and sulfur are the kinds of atoms always present in protein molecules
Sulfur molecules
In nature generally they are S8 molecules. It shows zero in that molecule.
72 grams SO2 (1 mole SO2/64.07 grams)(6.022 X 1023/1 mole SO2) = 6.8 X 1023 molecules of sulfur dioxide ============================
There are two elements present in sulfur trioxide, which are: Sulfur and Oxygen.The following formula represents sulfur trioxide: SO3As there is one atom of sulfur and three atoms of oxygen (trioxide).
The formula for sulfur trioxide is SO3. The molecular weight is 80.06. The atomic weight of sulfur is 32.06. Therefore, the fraction by weight of sulfur in sulfur trioxide is 32.06/80.06 is 0.4004, to the justified number of significant digits, so that 9.96 grams of sulfur trioxide contains 3.988 grams of sulfur. The number of atoms present in 3.988 grams of sulfur therefore is Avogadro's Number X (3.988/80.06) or 3.000 X 1021 atoms, to the justified number of significant digits. (Note: A depressed final digit in a decimal means that the digit may not be significant.)
Sulfur is a chemical element; the smallest unit is the sulfur atom.
generally sulphur shows many numbers. It has 0 in S8 molecules.
