Explanation by: Christine A [ Return to question menu
]Answer 1
1 x 10 ^{1} kgINCORRECT This answer would imply that a chicken egg has a mass of approximately ten kilograms (22 pounds, about the size of a small dog). Chicken eggs are not normally this large. Thus, this cannot be the correct answer. return to top
Answer 2
1 x 10 ^{2} kgINCORRECT 1 x 10 ^{2} kilograms is equal to 100 kilograms. This is approximately the mass on an NFL linebacker.
Chicken eggs are not normally as massive as a human. Because of this, answer 2
must be incorrect.

Answer 3
1 x 10 ^{-1} kgCORRECT You cracked the question! 1/10 of a kilogram is equal to 100 grams, which is roughly the mass of an average chicken egg. return to top
Answer 4
1 x 10 ^{-4} kgINCORRECT This is incorrect because 1 x 10 ^{-4} kilograms is equal to .0001 kilograms, or roughly the mass of a grain of brown rice;
this is too small to be an egg, so answer 4 must be incorrect.

What's this question really asking?
