Answer:

245*10⁻⁶ kg

Explanation:

Given:

Mass of nitrogen in a glass bulb = 245 mg

In order to convert mass from mg (milligrams) to kg (kilograms) use the following relation

1 mg = 0.001 gram = 10⁻³ g

1 g = 0.001 kg = 10⁻³ kg

Therefore,

1 mg = 10⁻⁶ kg

The given mass of 245 mg would correspond to :

[tex]\frac{245 mg * 10^{-6} kg}{1 kg} = 245*10^{-6} kg[/tex]
