Step-by-step explanation
To convert units, construct a fraction that is equal to 1, multiply the original measurement by that fraction, and simplify.
we need to know the equivalence, in this case
as we need to convert form mg to g, we need to cancel the ( mg) units, so the fraction we need will have mg in the denominatror
Now, just mutlply the given measure by the fraction ( check we are multiplying by 1, so we are not afffecting the amount)
hence
therefore the answer is 2g
