Answer 2

A. 2.43 kg x 1000 g/1 kg

Step-by-step explanation:

We know that the equivalence between grams and kilograms is

`1 kg = 1000 g`

So, if we want to convert a mass m from kg to g, we just need to multiply the value by the factor
`(1000 g)/(1 kg)`.

In this problem, the mass is

m = 2.43 kg

Therefore, multiplying by the factor above, we get

`m = 2.43 kg \cdot ( 1000 g)/(1 kg)`
