Answer:
2 × 10⁵
Explanation:
The total mass of the drug, ibuprofen = 10 kg
Kilograms and grams are related as:
1 kg = 1000 g
Also,
Grams and milligrams are related as:
1 g = 1000 mg
So,
1 kg = 10⁶ g
Mass of the drug, ibuprofen = 10 × 10⁶ mg = 10⁷ mg
Given, mass of tablet = 50 mg
So, number of tablets = total mass / Mass of 1 tablet = 10⁷ mg / 50 mg = 2 × 10⁵
<u>Number of 50 mg tablets = 2 × 10⁵</u>
