How do you find the percent of oxygen by mass in a compound?
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.
What is the percentage mass of oxygen in MgSO4?
The molar mass of MgSO4 is 120.37 g/mol. The molar mass of oxygen is 16.00 g/mol. To find the percentage mass of oxygen in MgSO4, we divide the molar mass of oxygen by the molar mass of MgSO4 and multiply by 100 to get 47.27%.
What is the percent by mass of oxygen in propanal CH3CH2CHO?
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%.
What is the mass percent of oxygen on SO2?
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%.
What is the percent by mass of oxygen in propanol?
The molar mass of propanol (C3H8O) is approximately 60.08 g/mol. Oxygen has a molar mass of 16 g/mol. To find the percent by mass of oxygen in propanol, divide the molar mass of oxygen by the molar mass of propanol and multiply by 100. This gives a percentage of around 26.6%.

What is the mass percent of oxygen in of N2O4?
The percent by mass of oxygen in N2O4 is 69,56 %.
What is the molar mass of oxygen gas?
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
What is the percent by mass of oxygen in propanol?
The molar mass of propanol (C3H8O) is approximately 60.08 g/mol. Oxygen has a molar mass of 16 g/mol. To find the percent by mass of oxygen in propanol, divide the molar mass of oxygen by the molar mass of propanol and multiply by 100. This gives a percentage of around 26.6%.
What is the molar mass for Oxygen dichloride OCl2?
The molar mass of oxygen dichloride (OCl2) is approximately 87.45 grams per mole. This is calculated by adding the molar mass of oxygen (16 g/mol) and twice the molar mass of chlorine (35.5 g/mol) because there are two chlorine atoms in OCl2.
The number of moles of oxygen in the reaction vessel is?
To calculate the number of moles of oxygen in the reaction vessel, you need to know the amount of oxygen in grams and its molar mass. Then divide the mass of oxygen by its molar mass to obtain the number of moles. The formula to calculate the number of moles is: moles = mass / molar mass.
Phenylalanine C9H11NO2 is an amino acid used to make proteins It has a molar mass of 165.19 g mol What is the mass percent of oxygen in phenylalanine?
The molar mass of oxygen in phenylalanine is 16.00 g/mol. To calculate the mass percent of oxygen in phenylalanine, divide the molar mass of oxygen by the molar mass of phenylalanine, then multiply by 100. (16.00 g/mol / 165.19 g/mol) * 100 = 9.68% Therefore, the mass percent of oxygen in phenylalanine is approximately 9.68%.
What is the percent by mass of oxygen in xenon tetroxide?
The molecular formula of xenon tetroxide is XeO4. To find the percent by mass of oxygen in XeO4, we calculate the molar mass of oxygen (O) and divide it by the molar mass of XeO4, then multiply by 100 to get the percentage. The molar mass of oxygen is 16.00 g/mol and the molar mass of XeO4 is 195.29 g/mol. Therefore, the percent by mass of oxygen in XeO4 is (4 x 16.00 / 195.29) x 100 ≈ 32.77%.
