Question

using the table of equalities, calculate the number of ounces (oz) in 22 pounds (lb). remember to select an answer with the correct number of significant figures.

some common equalities

quantity	metric (si)	u.s.	metric - u.s.
volume	1 l = 1000 ml<br>1 dl = 100 ml<br>1 ml = 1 cm³	1 qt = 4 cups<br>1 qt = 2 pt<br>1 gal = 4 qt	946 ml = 1 qt<br>1 l = 1.06 qt
mass	1 kg = 1000 g<br>1 g = 1000 mg	1 lb = 16 oz	1 kg = 2.20 lb<br>454 g = 1 lb
time	1 h = 60 min<br>1 min = 60 s	1 h = 60 min<br>1 min = 60 s

16 ounces
3.5×10² ounces
14 ounces
22 ounces

Explanation:

Step1: Identify the conversion factor

From the table, 1 lb = 16 oz.

Step2: Set up the conversion

We have 22 pounds. To convert to ounces, we multiply the number of pounds by the conversion - factor. So, the number of ounces = 22 lb×16 oz/lb.

Step3: Calculate the result

22×16 = 352 ounces. In scientific notation, 352 = 3.52×10². Rounding to two significant figures (since 22 has two significant figures), we get 3.5×10² ounces.

Answer:

3.5×10² ounces
