Asample of nitrogen in a glass bulb has a mass of 245 mg what is its mass in kilograms

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 :

the maximum mass of nh3 is nh3 in grams
