answer:
mass = 58.944 g
given data:
number of moles of SO₂ = 0.921 mol
mass of SO₂ = ?
solution:
formula:
number of moles = mass/ molar mass
- first of all we will calculate the molar mass.
SO₂ = 32 + 16×2 = 64 g/mol
- now we will put the values in formula.
- number of moles = mass/ molar mass
0.921 mol = mass /64 g/mol
mass = 0.921 mol × 64 g/mol
mass = 58.944 g
The mass of 0.921 mol sulfur dioxide gas has been 59.0361 g.
Moles have been defined as the mass of the substance with respect to the molar mass.
Moles have been expressed as:
[tex]\rm Moles=\dfrac{Mass}{Molar\;mass}[/tex]
The molar mass has been the sum of the constituents elements in the formula unit of a compound.
The molar mass of sulfur dioxide has been 64.1 g/mol
Substituting the values for the mass of 0.921 moles gas
[tex]\rm 0.921\;mol=\dfrac{Mass}{64.1\;g/mol} \\Mass=0.921\;\mol\;\times\;64.1\;g/mol\\Mass=59.0361 \;g[/tex]
The mass of 0.921 mol sulfur dioxide gas has been 59.0361 g.
