Weight of the student = 3.3 lb

The conversion factor =

Therefore, weight of the student in terms of g =  3.3lb x = 1496.88 g

= 1.497x  103 g                                                

= 1.5 x 103 g (rounding off to two significant figures. The leftmost digit is more than 5 so the preceding number is increased by 1)

The weight loss by  the student in terms of g is 1.5 x103 g
