There are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.
<h3>Disaccharides</h3>
- Disaccharides are carbohydrate compounds containing two monosaccharide units linked together by glycosidic bonds
Examples of disaccharides include sucrose and maltose.
- The ratio of hydrogen to oxygen atoms in a carbohydrate is always a 2:1.
For example, the formula of sucrose is C₁₂H₂₂O₁₁
> The ratio of hydrogen to oxygen atoms is 2;1
Therefore, there are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.

Answer/Explanation:
Recall: 
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1
