The dosage of a chemical like alum in water treatment is calculated by multiplying the dosage per litre with the total volume of water treated, and then converting units appropriately.
\( \text{Total Alum Used (mg)} = \text{Volume of water (litres)} \times \text{Dosage (mg/litre)} \)
\( \text{Convert mg to kg: } \frac{\text{mg}}{1,000,000} \)
Given:
Volume of water = 16 million litres = \( 16,000,000 \, \text{litres} \)
Alum dosage = \( 30 \, \text{mg/litre} \)
Calculation:
Total alum used in mg:
\( 16,000,000 \times 30 = 480,000,000 \, \text{mg} \)
Convert mg to kg:
\( \frac{480,000,000}{1,000,000} = 480 \, \text{kg} \)
