Chapter 2: Q.2.55 (page 45)

Perform each of the following conversions using metric conversion factors:

a. 44.2mL to liters

b. 8.65m to nanometers

c. 5.2×108g to megagrams

d. 0.72Ks to milliseconds

Short Answer

Expert verified

a.0.0422L

b.8.65×109nm

c.5.2×102Mg

d.7.2×105ms

Step by step solution

01

Part (a) Given Information

Unit conversion for mL to L

02

Part (a) Explanation

The metric unit of volume is LitersL. In hospitals or laboratories volume is measured in millilitersmL.

localid="1651724747264" 1mL=1000L

So, 44.2 mL will be:

03

Part (b) Given Information

Unit conversion of m to nm

04

Part (b) Explanation

The metric and SI unit of length is meters m

role="math" localid="1651725113400" 1m=109nm

So, 8.65 m will be:

8.65m=8.65×109nm

05

Part (c) Given Information

Unit conversion of g into Mg

06

Part (c) Explanation

In laboratories, the mass is measured in megagramsMg.

1g=10-6Mg

So, 5.2×108gwill be

5.2×108g=5.2×108×10-6=5.2×102Mg

07

Part (d) Given Information

Unit conversion of Ks to ms

08

Part (d) Explanation

The unit conversion for Ks into ms can be given as:

1Ks=107ms

So, 0.72 Ks will be

0.72Ks=0.72×107msor7.2×105ms
