Answer:
677.76 g of oxygen needed.
Explanation:
Given data:
Mass of glucose = 635.2 g
Mass of oxygen needed = ?
Solution:
Chemical equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
Number of moles of glucose:
Number of moles = mass/ molar mass
Number of moles = 635.2 g / 180.156 g/mol
Number of moles = 3.53 mol
Now we will compare the moles of glucose with oxygen.
C₆H₁₂O₆ : O₂
1 : 6
3.53 : 6×3.53 = 21.18 mol
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 21.18 g × 32 g/mol
Mass = 677.76 g

Nucleic acids are hydrocarbons that also contain nitrogen, phosphorus and oxygen elements.
Hydrocarbons are long chains of carbon that have additional bonds exclusively with hydrogen atoms. They are hydrophobic, or not soluble in water. Nucleic acids are macromolecules that are made of units called nucleotides, they are mainly in two forms; the RNA and and the DNA. Both the RNA and DNA have a pentose sugar, a phosphate, and a nitrogen containing base.
