Calculate the mass of nitrogen in 1000 kg of urea, `CO(NH_(2))_(2)` (Answer corrected to the nearest kg).

Explanation

To calculate the mass of nitrogen in 1000 kg of urea, we will follow these steps:

### Step 1: Convert the mass of urea from kilograms to grams.
Given that 1 kg = 1000 grams,
\[ \text{Mass of urea} = 1000 \, \text{kg} \times 1000 \, \text{g/kg} = 10^6 \, \text{g} \]
