Question

1. fill in the number of atoms for each chemical formula. c₁₂h₂₂o₁₁ co₂ nac₃h₃o₂

Explanation:

Step1: Count atoms in $C_{12}H_{22}O_{11}$

Carbon: 12, Hydrogen: 22, Oxygen: 11. Total = 12 + 22+ 11 = 45

Step2: Count atoms in $CO_{2}$

Carbon: 1, Oxygen: 2. Total = 1 + 2 = 3

Step3: Count atoms in $NaC_{3}H_{3}O_{2}$

Sodium: 1, Carbon: 3, Hydrogen: 3, Oxygen: 2. Total = 1+3 + 3+ 2 = 9

Answer:

$C_{12}H_{22}O_{11}$: 45 atoms
$CO_{2}$: 3 atoms
$NaC_{3}H_{3}O_{2}$: 9 atoms
