If a dog has a mass of 18.1 kg, what is its mass in the following units? use scientific notation in all of your answers. a) what is the dogs mass in grams? b)what is the dogs mass in milligrams? c)what is the dog's mass in micrograms?

Dog's mass is 1.81 ×10⁴ g, 1.81 ×10⁷ mg and 1.81 ×10¹⁰ μg

Explanation:

1 kg = 1000 g  (1×10³)

1 kg = 1000000 mg ((1×10⁶)

1kg = 1000000000 μg ((1×10⁹)

18.1 kg / 10 = 1.81

1.81 ×10⁴ g

1.81 ×10⁷ mg

1.81 ×10¹⁰ μg

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
