Reveal answer Fill a bubble to check yourself
B Correct answer

$1 \ \text{ g} =1000\  \text{mg}$

$\Rightarrow 1 \  \text{mg}=.001 \ \text{ g}$
$\Rightarrow 90000 \ \text{mg}  =.0001\times90000=90 \ \text{ g}$
$1 \ \text{kg}=1000 \ \text{ g}$
$\Rightarrow 1 \ \text{g}=.001 \ \text{ kg}$
$\Rightarrow 90 \ \text{g} =90\times.001=.09 \ \text{ kg}$
Option B is correct
