Answer:

Incorrect

Explanation:

Given that,

The mass of a boulder, m = 22 kg

We need to find the weight of the student in pounds.

We know that,

1 pound = 454 g

or

1 g = (1/454 pounds)

22 kg = 0.022  grams

So,

0.022 grams = \dfrac{0.022}{454}\ pounds

= 0.000048 pounds

The student says the weight is 0.048 pounds. It means he was incorrect.
