Answer:

1 200 000 000 000 000 000 000 000 H⁺ ions

Step-by-step explanation:

Assume that the concentration of H⁺ ions in stomach ions is 2.0 mol·L⁻¹.

Then, we have 2.0 mol of H⁺ ions

There are 6.02 × 10²³ H⁺ ions in 1 mol.

2.0 mol = 2.0 × 6.022 × 10²³/1

             = 1.2 × 10²⁴ H⁺ ions

             = 1 200 000 000 000 000 000 000 000 H⁺ ions
