147.2 grams C6H12O6 (1 mole C6H12O6/180.156 grams)(6 moles O/1 mole C6H12O6)(16.0 grams/1 mole O)
= 78.4 grams oxygen

how many grams of glucose must be added to 525g of 2.5 percent leg mass glucose solution?and give the furmela?
The percentage of oxygen is 54,84 %.
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.

A molecule of glucose contains 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. Their atomic masses are 12, 1 and 16 respectively. Therefore the atomic mass of glucose is 6x12+12x1+6x16=180 grams per mole.
Molecular mass of C6H12O6 = 6(12.0) + 12.0 + 6(16.0) = 180.0 Amount of glocose = 5.23/180.0 = 0.0291mol 1 mol of glucose contains 6.02 x 1023 molecules (avogadro constant). In each molecule of glucose there are 6 oxygen atoms. Number of oxygen atoms = 6 x 0.0291 x 6.02 x 1023 = 1.05 x 1023
The molar mass of oxygen is approximately 16 grams/mol. Therefore, the mass of 0.8 grams of oxygen is equivalent to 0.8/16 = 0.05 moles.
The molar mass of oxygen is approximately 16 grams/mol. Therefore, the mass of 3 moles of oxygen would be 3 moles * 16 grams/mole = 48 grams.
The molar mass of oxygen is approximately 16.00 grams per mole. Therefore, the mass of 1.0 mole of oxygen is 16.00 grams.
how many grams of glucose must be added to 525g of 2.5 percent leg mass glucose solution?and give the furmela?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
The molar mass of glucose is approximately 180.16 g/mol. Therefore, one mole of glucose weighs approximately 180.16 grams.
16 grams or 32 grams, depending on what you're looking at.The mass of one mole of oxygen atoms is about 16 grams, but oxygen gas exists as a molecule (O2) so 1 mole of (O2) is 32 grams.
The percentage of oxygen is 54,84 %.
Just about 16 grams as what you have written in you question is Avogadro's number, which is a mole of anything. Oxygen is 16 grams per mole.
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
what is the mass in grams of oxygen, is needed to complete combustion of 6 L of methane?
