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%.
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%.
