Question

Can anyone explain it to me, please?

Answer 1

Answer:

2×10² cg

Explanation:

We'll begin by converting each of the above to the same unit of measurement.

In this case, we shall convert each of the above to kg. This can be obtained as follow:

Conversion of cg to kg

1 cg = 1×10¯⁵ Kg

Therefore,

2×10² cg = 2×10² × 1×10¯⁵

2×10² cg = 0.002 kg

Conversion of dg to Kg

1 dg = 1×10¯⁴ kg

Therefore,

10 dg = 10 × 1×10¯⁴

10 dg = 0.001 kg

Conversion of mg to kg.

1 mg = 1×10¯⁶ Kg

Therefore,

2×10² mg = 2×10² × 1×10¯⁶

2×10² mg = 0.0002 kg

Conversion of ng to kg

1 ng = 1×10¯¹² kg

Therefore,

1×10⁵ ng = 1×10⁵ × 1×10¯¹²

1×10⁵ ng = 0.0000001 Kg

Summary

1. 2×10² cg = 0.002 kg

2. 10 dg = 0.001 kg

3. 2×10² mg = 0.0002 kg

4. 0.001 kg

5. 1×10⁵ ng = 0.0000001 Kg

From the above calculation, 2×10² cg is the highest mass.
