What mistake did carl make? carl makes the table below to determine the number of atoms of each element in the chemical formula 4ca(cio3)2. element calculation calcium 1x4 chlorine 1 x 2 oxygen 3 x 2 total atoms 4 2 6 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.

He did not multiply the chlorine and oxygen atoms by the coefficient 4

Explanation:

The correct answer is:

'He did not multiply the chlorine and oxygen atoms by the  coefficient 4'.

Explanation:

Number of atoms in

The 4 in front of molecular formula of calcium chlorate is its coefficient . it tells us about the molecules or moles of compound.

Number of calcium in 1 molecule of calcium chlorate = 1

Calcium atoms in 4 molecule of calcium chlorate = 1 × 4 = 4

Number of calcium in 1 molecule of calcium chlorate = 2

Chlorine atoms in 4 molecule of calcium chlorate = 2 × 4 = 8

Number of oxygen in 1 molecule of calcium chlorate = 3 × 2 = 6

Oxygen atoms in 4 molecule of calcium chlorate = 6 × 4 = 24

So, number of atoms of different elements calculated by Carl was wrong as he didn't multiplied the coefficient 4 with chlorine and oxygen atoms.
