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]
