Final answer:
The correct number of total atoms in Ca(C₂H₃O₂)₂ is 15, which comprises 1 calcium, 4 carbon, 6 hydrogen, and 4 oxygen atoms, while none of the answer choices provided from a to d correctly represent this total.
Step-by-step explanation:
The answer to the question How many atoms are in Ca(C₂H₃O₂)₂ is d. 6.
To calculate the number of atoms in Ca(C₂H₃O₂)₂, we need to understand the formula. This compound is calcium acetate, and it is made up of one calcium atom (Ca), four carbon atoms (2 C in each C₂H₃O₂ for a total of 4 C atoms), six hydrogen atoms (3 H in each C₂H₃O₂ for a total of 6 H atoms), and four oxygen atoms (2 O in each C₂H₃O₂ for a total of 4 O atoms). Adding these up: 1 Ca + 4 C + 6 H + 4 O equals 15 atoms in total.
However, the answer choices given from a to d do not match the correct number of atoms. The question may have an error or is missing context since none of the answer choices are correct.
