Answer:
Approximate weight of cell phone is between 100 gm to 200 gm.
1 Pound = 0.45359237 Kilograms

Because, 1 Kilogram = 1,000 gram
If, n=0
Weight of cell phone = 1272.7 grams=1.2727 Kg
when, n=1
Weight of cell phone = 12727 grams=12.727 Kg
n= -2,
Weight of cell phone = 12.727 grams
n=- 3
Weight of cell phone = 1.2727 grams
