Question

Which of the following mass units is the largest? a) 1 cg b) 1 dg c) 1 mg d) 1 ng

Answer 1

Which of the following mass units is the largest?

b) 1 dg

Answer 2

Answer: option b) 1 dg

Step-by-step explanation:

1) These are the different equivalences of those quantities:

a) 1 g = 100 cg ⇒ 1 cg = 0.01 g

b) 1 g = 10 dg ⇒ 1 dg = 0.1 g

c) 1 g = 1000 mg ⇒ 1 mg = 0.001 g

d) 1g = 10⁹ g ⇒ 1 ng = 10 ⁻⁹g

2) Now that you have all the masures in grams you can compare:

0.1g > 0.01g > 0.001g > 10 ⁻⁹g

3) So, the largest value is 0.1g which is 1 dg.
