Explanation:

Step1: Understand the units

Kilograms (kg) are used for much heavier objects. For example, a small child might have a mass around 10 - 30 kilograms. Grams (g) are used for lighter objects.

Step2: Relate to real - life objects

A dinner fork is a small, lightweight object. 70 kilograms is extremely heavy for a dinner fork. 70 grams is a more reasonable estimate as it is in line with the mass of small, everyday utensils.

Answer:

70 grams
