She should not have multiplied the sulfur atoms by the subscript 4.

She should not have multiplied the nitrogen atoms by the subscript 2.

She should not have multiplied the oxygen atoms by the coefficient 3.

She should not have multiplied the hydrogen atoms by the coefficient 3.

Gretchen Carr · Answer 1

She should not have multiplied the nitrogen atom by subscript 2.

Explanation:

Chemical formula:

3 (NH₄) ₂SO₄

Elements present in given formula:

Nitrogen

Hydrogen

Sulfur

Oxygen

Total number of atoms of elements:

N = 3*1*2 = 6

H = 4*2*3 = 24

S = 1*3 = 3

O = 3*4 = 12

The number nitrogen atoms are six. Elena did mistake by counting the number of nitrogen. She should didn't multiplied the nitrogen atom by subscript 2.
