What percentage of sugar is oxygen?
In a sugar molecule, oxygen typically makes up around 53% of the total molecular weight.
What is the percentage of oxygen in sodium oxide?
The percentage of oxygen in sodium oxide is 72.7% as the chemical formula for sodium oxide is Na2O, which contains 2 oxygen atoms and 1 sodium atom. To calculate the percentage of oxygen, you divide the molar mass of oxygen by the molar mass of sodium oxide and multiply by 100.
What is the percentage of oxygen by mass in water?
The percentage of oxygen by mass in water is approximately 88.8%.
Does compressed oxygen have a weight?
actually compressed oxygen does actually have weight.
What percentage of the air around us is oxygen?
The percentage of oxygen in the atmosphere is 20.75%. The atmosphere has many other elements that we breathe in besides oxygen. Oxygen needs to be present for life on earth.
What element that makes up the greatest percentage of weight in the body?
Oxygen is the element that makes up the greatest percentage of weight in the body, comprising about 65% of the body's mass.

Percent of elements in the water?
Since water is made from two atoms of hydrogen and one atom of oxygen, the percentage of water that is hydrogen is 66% and the percentage of water that is oxygen is 33%. Note that is is NOT percentage of the formula by weight, just by count.
What percent of potaasium dihromate K2Cr2O7 oxygen?
The molecular formula for potassium dichromate is K2Cr2O7. The percentage of oxygen in potassium dichromate is calculated as follows: Molecular weight of oxygen: 16 g/mol Molecular weight of K2Cr2O7: 294 g/mol Percentage of oxygen in K2Cr2O7: (16 g/mol / 294 g/mol) * 100% = 5.44% Therefore, oxygen constitutes approximately 5.44% of the compound potassium dichromate.
What is the percentage of oxygen in sodium oxide?
The percentage of oxygen in sodium oxide is 72.7% as the chemical formula for sodium oxide is Na2O, which contains 2 oxygen atoms and 1 sodium atom. To calculate the percentage of oxygen, you divide the molar mass of oxygen by the molar mass of sodium oxide and multiply by 100.
How do yo calculate the percentage of oxygen in NiSO4 7H2O?
molecular weight of NiSO4.7H2O is 1101.3 and it has 11 oxygens. So percentage of oxygen = (7 x 16) / 1101.3 = 112 / 1101.3 = 0.102 or 10.2%
What is the percentage of oxygen to the nearest tenth in this compound Ba OH 2 8H2O?
The relative molecular weight of the compound nickel (II) sulphate heptahydrate NiSO4 7H2O is 280. 86. The total mass of oxygen in the compound is 176 g. Therefore the total percentage of oxygen to the nearest tenth is 60 percent
What is the percentage of oxygen in sucrose?
The percentage of oxygen in sucrose is 51,41549 %.
What is the percentage composition of oxygen in C7H15NO3?
The percentage of oxygen (in mass) is 29,776 %.
What is weight of oxygen?

How much does the human brain weigh as a percentage of total body weight?
The brain only represents 2% of our total body weight. Interestingly, it consumes 25% of the body's oxygen.
How do you calculate the theoretical mass percentage of oxygen in potassium chlorate?
To calculate the theoretical mass percentage of oxygen in potassium chlorate, you would use the formula weight of oxygen divided by the formula weight of the compound (potassium chlorate) multiplied by 100. The formula weight of oxygen is 16.00 g/mol and the formula weight of potassium chlorate (KClO3) is 122.55 g/mol. So, (16.00 g/mol / 122.55 g/mol) * 100 = 13.06%.
