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%.
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%.
What are the two elements that make up 75 percent of the total mass of the crustal rocks of the earth?
Oxygen and silicon are the two elements that make up 75 percent of the total mass of the crustal rocks on Earth.
A compound is formed when 48 grams of carbon 8 grams of hydrogen and 68 grams oxygen combine what is the percent by mass of oxygen?

What is the mass percent of oxygen in of N2O4?
The percent by mass of oxygen in N2O4 is 69,56 %.
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%.
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 mass percent of oxygen in the compound?
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%.
What is the mass percent of oxygen (O) in SO2?
(16.0g + 16.0g)/(32.1g + 16.0g + 16.0g) x 100 %
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 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 correct chemical equation for the following mass percent of oxygen in sodium oxide?
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.
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 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%.
