Choose the best estimate for the mass of a can of soup 300g or 300mg or 34kg

Question

Answer please?

Answer 1

Let's put these in terms of pounds, which is probably more familiar.

454 g = 1 lb

300 g x 1 lb/454 g = 0.66 lbs

300 mg x 1 g/1000 mg x 1 lb/454 g = 0.00066 lbs

34 kg x 1000 g/kg x 1 lb/454 g = 74.8 lbs

 

It seems that a can of soup would be closer to about 0.67 lbs, so it would most likely be 300 g
