(iii)
Answer

2.5365×10−22.5365 \times 10^{-2} kg

Explanation

To convert the given values into basic units, we use the factor label method or dimensional analysis. The basic SI unit for length is the meter (m) and for mass is the kilogram (kg). We use the standard conversion factors: 1 pm=10−12 m1 \text{ pm} = 10^{-12} \text{ m} and 1 mg=10−6 kg1 \text{ mg} = 10^{-6} \text{ kg}.
