The percent by mass of oxygen in N2O4 is 69,56 %.
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.
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%.
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.
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.
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%.
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 β 32.77%.
The molar mass of lithium oxide (Li2O) is calculated by adding the molar masses of lithium (Li) and oxygen (O). Molar mass of Li = 6.94 g/mol Molar mass of O = 16.00 g/mol Molar mass of Li2O = 2*(molar mass of Li) + molar mass of O = 2*(6.94) + 16.00 = 14.88 + 16.00 = 30.88 g/mol
