If a dog has a mass of 20.5 kg, what is its mass in the following units? Use scientific notation in all of your answers. (a) What is the dog's mass in grams? × 10 g (b) What is the dog's mass in milligrams? × 10 mg (c) What is the dog's mass in micrograms? × 10 μ g
Homework Answers
a)
Conversion to be used:
1 Kg = 1000 g
mass = 20.5 Kg
= 20.5 * 1000 g
= 2.05*10^4 g
Answer: 2.05*10^4 g
b)
Conversion to be used:
1 Kg = 1000 g
1 g = 1000 mg
mass = 20.5 Kg
= 2.05*10^4 g
= 2.05*10^4 * 1000 mg
= 2.05*10^7 mg
Answer: 2.05*10^7 mg
c)
Conversion to be used:
1 Kg = 1000 g
1 g = 1.0*10^6 ug
mass = 20.5 Kg
= 2.05*10^4 g
= 2.05*10^4 * 1.0*10^6 ug
= 2.05*10^10 ug
Answer: 2.05*10^10 ug
