To round the number 482.65 g to 2 significant figures, we consider the first two digits, which are '4' and '8'. The third digit is '2', which is less than 5, so we do not round up. Therefore, 482.65 rounded to 2 significant figures is 480 g.

Next, we convert 480 g to scientific notation. In scientific notation, 480 can be expressed as:

\[ 4.8 \times 10^2 \]

So the final answer, rounded to 2 significant figures and in scientific notation, is:

**4.8 × 10² g**.
