Answer 1

ANSWER:

45.0 g

STEP-BY-STEP EXPLANATION:

After rounding to represent the given data to three significant figures, we have to write it down to one decimal place.

So we need to focus on the second decimal place i.e 8 as it is greater than 5 therefore we have to add one (1) to the first decimal place to do the rounding.

$44.981=45.0$
