Answer :
The question is basically asking us to substitute 2.5 kgs for grams, and the answer is 2500 grams. "kilo" means thousand so a Kilogram is a thousand grams. 2 kilograms are 2000 grams and 2.5 kilograms are 2500 grams. When you are asked to express a kilogram mass in grams, all you need to do is to multiply it by a 1000.
Kilograms and grams are units used to measure masses.
1000 grams are equivalent to 1 kg.
kilograms are used when there are larger masses, for simplicity and ease to make the numbers smaller we convert grams to kilograms
since 1 kg equals - 1000 g
then 2.5 kg equals - 1000 g/kg x 2.5 kg = 2500 g
the mass in grams is 2500 g
