Question

the chemical formula for sucrose is shown below
c₁₂h₂₂o₁₁
how many atoms of each element are in one molecule of sucrose?
a 22 carbon atoms, 11 hydrogen atoms, and 12 oxygen atoms
b 22 carbon atoms, 12 hydrogen atoms, and 11 oxygen atoms
c 11 carbon atoms, 12 hydrogen atoms, and 22 oxygen atoms
d 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms

Explanation:

Step1: Analyze chemical formula

The chemical formula of sucrose is $C_{12}H_{22}O_{11}$. The sub - script numbers indicate the number of atoms of each element in one molecule.

Step2: Determine number of carbon atoms

The sub - script of $C$ is 12, so there are 12 carbon atoms.

Step3: Determine number of hydrogen atoms

The sub - script of $H$ is 22, so there are 22 hydrogen atoms.

Step4: Determine number of oxygen atoms

The sub - script of $O$ is 11, so there are 11 oxygen atoms.

Answer:

D. 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms
