Answer: 1. Cardenolides, with the chemical formula CH₁₈C₂₀H₁₅CHCO₂ have (D) 23 carbon atoms, 34 hydrogen atoms, and 2 oxygen atoms.
Milkweed contains a poison known as cardenolides. The chemical formula for cardenolides CH₁₈C₂₀H₁₅CHCO₂.
The subscripts in the formula represent the atomicities, that is the number of atoms of each element in each part of the formula.
We can calculate the total number of atoms of each element by adding its atomicities.
Carbon atoms
Hydrogen atoms
Oxygen atoms

2.Mercury (I) phosphate with the chemical formula (Hg2)3(PO4)2 has 16 atoms.
Number of Hg atoms = 2x3 = 6
Number of P atoms = 2 x 1 = 2
Number of O atoms = 4x2 = 8
Sum of all the atoms = 6+2+8
= 16 atoms
