Mass to charge ratio for A⁺ = 1.97 × 10⁻⁷ Kg/C
Here you see A⁺ has one unit positive charge .
Means, charge on A⁺ = charge on a proton = 1.6 × 10⁻¹⁹ C
Now, mass of A atom = mass to charge ratio × charge on A⁺
= 1.97 × 10⁻⁷ × 1.6 × 10⁻¹⁹ Kg
= 3.152 × 10⁻²⁶ Kg
Hence, mass of A atom = 3.152 × 10⁻²⁶ Kg
