To find the percent of oxygen by mass in trinitrotoluene (TNT), you need to know the molecular formula of TNT. TNT contains 30.4% oxygen by mass, so in 0.370 kg of TNT, the mass of oxygen would be 0.370 kg * 0.304 = 0.11248 kg. To convert this to a percentage, divide the mass of oxygen by the total mass of TNT (0.370 kg) and multiply by 100 to get 30.4%.

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 make up 10 to 30 percent of the cell mass?
oxygen
Aspartic acid C4H7NO4 is an amino acid used to make proteins It has a molar mass of 133.11 g mol What is the mass percent of oxygen in aspartic acid?
To find the mass percent of oxygen in aspartic acid, we calculate the molar mass contribution of oxygen (O) in the compound and divide it by the total molar mass of the compound, then multiply by 100%. Aspartic acid has 4 oxygen atoms contributing to a total molar mass of 64.00 g/mol. Therefore, the mass percent of oxygen in aspartic acid is (64.00 g/mol / 133.11 g/mol) * 100% = 48.10%.

How find percent compsotion of oxygen in Na2O?
To find the percent composition of oxygen in Na2O, first calculate the molar mass of Na2O (Sodium oxide) which is 61.98 g/mol. The molar mass of oxygen is 16 g/mol. Then, calculate the percent composition of oxygen in Na2O using the formula: (16 g/mol / 61.98 g/mol) * 100. This gives you the percent composition of oxygen in Na2O, which is approximately 25.8%.
What is the mass percent of oxygen in SO2?
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%.
What is the mass percent of oxygen in estriol?
Estriol (C18H24O3) contain 16,644 % oxygen.
What is the approximate percent by mass of oxygen in SO3?
The molar mass of SO3 is 80.06 g/mol, with oxygen contributing 48.00 g/mol, which is 60% of the total molar mass. Therefore, the approximate percent by mass of oxygen in SO3 is 60%.
If 230 g sample of a compound contains 136.6 g of carbon 26.4 g of hydrogen and 31.8 g of nitrogen The rest is oxygen What is the mass percent of oxygen in the compound?
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of carbon, hydrogen, and nitrogen. The total mass of the compound is 136.6 g (C) + 26.4 g (H) + 31.8 g (N) = 194.8 g. The mass of oxygen can be calculated by subtracting the total mass of the compound from the given mass of the sample: 230 g - 194.8 g = 35.2 g. Therefore, the mass percent of oxygen in the compound is (35.2 g / 230 g) x 100% ≈ 15.3%.
What is the mass percent of oxygen in phenylalanine?
The molecular formula of phenylalanine is C9H11NO2. To calculate the mass percent of oxygen in phenylalanine, we first need to calculate the molar mass of the compound. This molar mass is found to be 165.19 g/mol. The mass percent of oxygen in phenylalanine is then found to be (32.00 g/mol / 165.19 g/mol) * 100 ≈ 19.38%.
Why is it inaccurate to say that CO is 50 percent oxygen?
Because the mass of carbon is not the same as that of oxygen.
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%.
What is the percent of the mass of oxygen in xenon tri oxide?
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%.
What make up 10 to 30 percent of the cell mass?
