Carl makes the table below to determine the number of atoms of each element in the chemical formula 4Ca(ClO3)2. A table with 3 c
olumns and 2 rows. The first column labeled element has entries calcium, chlorine, oxygen. The second column labeled calculation has entries 1 times 4 , 1 times 2, 3 times 2. The third column labeled total atoms has entries 4, 2, 6. What mistake did Carl make? He did not multiply the calcium atoms by the subscript 2. He did not add the coefficient 4 to the chlorine and oxygen atoms. He did not add the subscript 2 to the calcium atoms. He did not multiply the chlorine and oxygen atoms by the coefficient 4.
