To find the percent mass of oxygen in xenon trioxide (XeO3), we first calculate the molar mass of XeO3. Xenon has a molar mass of 131.3 g/mol, and oxygen has a molar mass of 16.00 g/mol. So the molar mass of XeO3 is 131.3 + 3(16.00) = 179.3 g/mol. The mass of oxygen in XeO3 is 3(16.00) = 48.00 g. Therefore, the percent mass of oxygen in XeO3 is (48.00 g / 179.3 g) x 100% ≈ 26.73%.
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
To find the percent by mass of oxygen in propanal (CH3CH2CHO), calculate the molar mass of oxygen (O) and the molar mass of the entire compound. Then divide the molar mass of oxygen by the molar mass of the entire compound and multiply by 100 to get the percentage. In this case, the percent by mass of oxygen in propanal is around 47.3%.
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
To determine the mass percent of oxygen in a compound, you would calculate the mass of oxygen in the compound and then divide it by the total mass of the compound, before multiplying by 100. The formula is: (mass of oxygen in compound / total mass of compound) x 100%.

The mass of 3,28 moles of dinitrogen tetroxide is 301,8 g.
The percent by mass of oxygen in N2O4 is 69,56 %.
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of magnesium and oxygen: 14.5 g + 3.5 g = 18.0 g. Then, use the formula for mass percent: (mass of oxygen / total mass) × 100%. Thus, the mass percent of oxygen is (3.5 g / 18.0 g) × 100% ≈ 19.44%.

The molar mass of SO2 is 64.07 g/mol. Since oxygen has a molar mass of 16 g/mol and there are 2 oxygen atoms in SO2, the total mass of oxygen in SO2 is 32 g. Therefore, the mass percent of oxygen in SO2 is 32/64.07 * 100% = 50.05%.
The mass number of xenon is 131.
The molar mass of SO2 is 64.07 g/mol. Oxygen has a molar mass of 16.00 g/mol. To calculate the mass percent of oxygen in SO2, we can divide the molar mass of oxygen (32.00 g) by the molar mass of SO2 (64.07 g) and multiply by 100 to get 50.05%.
