Answer 2

Answer:

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.
