3. An object weighs 8.22 lbs. What is the mass in grams?​
Rainbow [258]

Answer:

The correct answer is 372852.9 g.

Explanation:

First, we must look for the relationship between the masses in grams and pounds.

To get an approximate result, the relationship between pounds and grams found is:

1 lbs = 453.592 g

Now we must use this relationship as a conversion factor in the following way:

8.22 lbs * \frac{453.592 g}{1 lbs} = 372852.9 g

The mass expressed in grams for 8.22 lbs is 372852.9 g.

Have a nice day!
