Sulfur trioxide (SO3) contains about 40% sulfur by mass.
The percent composition of sulfur in a compound is calculated by dividing the mass of sulfur by the total mass of the compound and then multiplying by 100. For example, in sulfuric acid (H2SO4), since the molar mass of sulfur is 32 g/mol and the total molar mass of sulfuric acid is 98 g/mol, the percent composition of sulfur would be (32/98) x 100 = 32.65%.

The chemical formula for sodium oxide is Na2O. To determine the mass percent of oxygen in Na2O, we need to calculate the molar mass of oxygen (O) and sodium oxide (Na2O), then use these values to calculate the mass percent of oxygen in Na2O.
The molar mass of sulfur dioxide (SO2) is 64.06 g/mol. The molar mass of sulfur is 32.06 g/mol. Calculate the mass percent of sulfur in SO2 using the formula (mass of sulfur / mass of SO2) x 100%. This gives a mass percent of sulfur in SO2 as 50%.
To determine the percent sulfur by mass in SO3, you need to consider the molar mass of each element. In SO3, there is one sulfur atom with a molar mass of 32.06 g/mol and three oxygen atoms with a molar mass of 16.00 g/mol each. Calculate the total molar mass of SO3, then determine the mass contributed by sulfur in that total mass to find the percent sulfur by mass.
H2S2O8 has a larger percent by mass of sulfur because it contains two sulfur atoms in each molecule compared to one sulfur atom in H2SO3.

Sulfur trioxide (SO3) contains about 40% sulfur by mass.
Sulfur dioxide (SO2) is composed of one sulfur atom and two oxygen atoms. To calculate the percent sulfur, divide the atomic mass of sulfur by the molecular mass of sulfur dioxide, then multiply by 100. The percent sulfur in sulfur dioxide is approximately 50%.
The percent composition of sulfur in a compound is calculated by dividing the mass of sulfur by the total mass of the compound and then multiplying by 100. For example, in sulfuric acid (H2SO4), since the molar mass of sulfur is 32 g/mol and the total molar mass of sulfuric acid is 98 g/mol, the percent composition of sulfur would be (32/98) x 100 = 32.65%.
The oxide N2O3 has a lower percent of mass nitrogen.

h2s2o3 has the largest because it has more sulfur
To find the percent composition, first calculate the total mass by adding the masses of Argon and Sulfur. Then, determine the percent composition of each element by dividing the mass of that element by the total mass and multiplying by 100. In this case, the percent composition of Argon is about 87.1%, and the percent composition of Sulfur is about 12.9%.
