Premarins main constituent is estrone (50%),
Sodium 13-methyl-17-oxo-3-sulfonatooxy-7,8,9,11,12,14,15,16-octahydro-6H-cyclopenta[a]-phenanthrene, C18H21O(SO4Na), 372.412 g/mol
So there is 100%*[5*16.0 (g O/mol) / 372.412 (g/mol)] = 21.5% Oxygen in estrone.

What is the atomic mass of o?
The atomic mass of oxygen (O) is approximately 16 atomic mass units.
How do I calculate the percent composition of the following by mass with 3 significant figures O in Na2SO4?
Add up the compound's molar mass: Na=2(23), S=1(32), O=4(16). Sum is 142. Oxygen's part of that total is 64 (16x4). Percent is part/total, so 64/142 = 0.4507 = 45.1%.
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%.
Which element has an atomic mass of 16.00?
the element that has an atomic mass of 16.00 is sulfer.
What is the mass of O?
The molar mass of oxygen (O) is approximately 16.00 g/mol.
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 percent by mass of oxygen in MgO?
The molar mass of MgO is 40.3 g/mol (24.3 g/mol for Mg and 16 g/mol for O). The mass of oxygen in MgO is 16 g, so the percent by mass of oxygen is (16 g / 40.3 g) x 100% ≈ 39.7%.
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 percent composition of O in BeO?
The percent composition of oxygen in BeO is approximately 89.7%. This can be calculated by dividing the molar mass of oxygen by the molar mass of BeO and multiplying by 100.
What is the mass percent of oxygon (O) in SO2?
The molar mass of SO2 is 64.06 g/mol. Oxygen contributes 32 g/mol to this molar mass, so the mass percent of oxygen in SO2 is (32 g/mol / 64.06 g/mol) x 100, which is approximately 50%.
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.
What is the percent composition of FeO?
FeO is 50 mole % Fe and 50 mole % O FeO is 77.73 mass % Fe and 22.27 mass % O mass fraction X = molar mass X / (total molar mass of compound) mass % Fe = [atomic mass Fe] / ([atomic mass Fe] + [atomic mass O])
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%.
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 in oxygen SO2?
I assume you mean mass of oxygen % in SO2. This is calculated by finding the molecular weight of S and O (32 and 16 respectively) As there are 2 oxygens, 16 is multiplied by 2, = 32. put 32 over the total, = 32/64. Which equals 50%
What is the atomic mass of o?
The atomic mass of oxygen (O) is approximately 16 atomic mass units.
How do I calculate the percent composition of the following by mass with 3 significant figures O in Na2SO4?
Add up the compound's molar mass: Na=2(23), S=1(32), O=4(16). Sum is 142. Oxygen's part of that total is 64 (16x4). Percent is part/total, so 64/142 = 0.4507 = 45.1%.
