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

How many molecules of sulfur dioxide are present in 72 g of the substance?

To determine the number of molecules of sulfur dioxide in 72 g of the substance, we first need to calculate the number of moles of sulfur dioxide present. The molar mass of sulfur dioxide (SO2) is approximately 64 g/mol. Therefore, 72 g of sulfur dioxide is equal to 72 g / 64 g/mol = 1.125 moles. Next, we use Avogadro's number, which is 6.022 x 10^23 molecules/mol, to convert moles to molecules. Therefore, there are approximately 6.78 x 10^23 molecules of sulfur dioxide in 72 g of the substance.


How many molecules of sulfur dioxide are present in 1.60 moles of sulfur dioxide?

There are approximately 9.65 x 10^23 molecules of sulfur dioxide in 1.60 moles of sulfur dioxide. This is because one mole of any substance contains Avogadro's number of molecules, which is 6.022 x 10^23.


How many ATOMS of sulfur are present in 9.96 grams of sulfur 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.)


How many atoms of sulfur are present in 155 g of sulfur?

To determine the number of sulfur atoms in 155 g of sulfur, you first need to calculate the number of moles of sulfur present. The molar mass of sulfur is approximately 32.06 g/mol. By dividing the given mass by the molar mass, you find that there are approximately 4.83 moles of sulfur. Since one mole of sulfur contains Avogadro's number of atoms (6.022 x 10^23), you can calculate that there are approximately 2.91 x 10^24 sulfur atoms in 155 g of sulfur.


Why is the atomicity of sulfur 8 and chlorine is 2?

The atomicity of an element refers to the number of atoms present in a molecule of that element. Sulfur typically forms molecules with 8 atoms (S8) due to its ability to form a stable ring structure. Chlorine, on the other hand, exists as diatomic molecules (Cl2) because it is more stable when paired with another chlorine atom through a single covalent bond.

How many molecules of SO2 would be present per cubic metre if the world health organization has set a limit to the sulfur dioxide content of clean air of 3.10 X 10-6 mol of SO2 per cubic metre.?

To calculate the number of molecules of SO2 present per cubic meter, you can use Avogadro's number (6.022 x 10^23 molecules/mol). First, convert 3.10 x 10^-6 mol to molecules by multiplying by Avogadro's number to get 1.86 x 10^18 molecules of SO2 per cubic meter.
