What is the percentage mass of oxygen in morphine?
The chemical formula for morphine is C17H19NO3. To calculate the percentage mass of oxygen in morphine, determine the molar mass of oxygen in the formula (3(16 g/mol)) and divide by the molar mass of morphine (285 g/mol), then multiply by 100 to get the percentage. The percentage mass of oxygen in morphine is approximately 16.8%.
What is the percentage mass of oxygen in MgSO4?
The molar mass of MgSO4 is 120.37 g/mol. The molar mass of oxygen is 16.00 g/mol. To find the percentage mass of oxygen in MgSO4, we divide the molar mass of oxygen by the molar mass of MgSO4 and multiply by 100 to get 47.27%.
What is the percentage mass of oxygen in cocaine?
Cocaine is C17H21NO4 and has a molar mass of 303.353 g/mole. Mass of oxygen in cocaine is 4x16 = 64. So, % oxygen by mass is 64/303.353 (x100) = 21% (to 2 sig. figs)
What percentage of water is hydrogen?
By mole, water is 66.666r% hydrogen but by mass it is about 11.9% hydrogen.
What compound has the highest percent of hydrogen by mess Water or hydrogen proxide?
Water has a higher percentage of hydrogen by mass than does hydrogen peroxide, because the latter has equal numbers of hydrogen and oxygen atoms while the former has twice as many hydrogen atoms as oxygen atoms.
Percentage by mass of components of water?
11% Hydrogen and 89% Oxygen
What is the percentage of oxygen in the Earth's atmosphere by mass?
The percentage of oxygen in the Earth's atmosphere by mass is approximately 21.
What is the percentage composition of oxygen in C7H15NO3?
The percentage of oxygen (in mass) is 29,776 %.

Oxygen is the most abundant element in?
As mass percentage oxygen is the most abundant.
How do you find theoretical percent of water?
To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.
Water is 88.8 percent by mass oxygen How many grams of water would contain 2.45 kg of oxygen?
I believe you would divide the kg by 88.8 to get 1%, then multiply by 100 to get the total mass. If you want it in grams then multiply by 1000. The answer ends up as 2759 grams. Feel free to correct me if you think I am wrong.
