what is the charge of 96 amu of s 2

The sulphide ion is represented as:

S²⁻

This means one sulphur ion carries a charge of:

-2e

where e = 1.6 × 10⁻¹⁹ C

Step 1: Calculate charge on one S²⁻ ion

Charge = -2 × 1.6 × 10⁻¹⁹

= -3.2 × 10⁻¹⁹ C

Step 2: Understand the given mass

Atomic mass of sulphur ≈ 32 amu

So, 96 amu of sulphur corresponds to:

96 ÷ 32 = 3 sulphur ions

Step 3: Total charge

Total charge = 3 × (-3.2 × 10⁻¹⁹)

= -9.6 × 10⁻¹⁹ C

Final Answer

The charge of 96 amu of S²⁻ ions is:

-9.6 × 10⁻¹⁹ C
