Question

A student was directed to convert the mass of a boulder from kg to pounds.

Conversion factor: 1 pound = 454 g
The mass is 22 kg. The student calculated the weight to be 0.048 pounds.
Is this correct? If not, what went wrong?

Answer 1

Incorrect

Step-by-step 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 =
`(0.022)/(454)\ pounds`

= 0.000048 pounds

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