Answer:
2.5 mL
Explanation:
Step 1: Given data
- Concentration of the active ingredient (C): 5% v/v
- Volume of the medicine (V): 50 mL
Step 2: Calculate the amount of the active ingredient in the medicine
The concentration of the active ingredient is 5% v/v, that is, there are 5 mL of the active ingredient per 100 mL of the medicine. The volume of the active ingredient is 50 mL of the medicine is:
50 mL Med × 5 mL AI/100 mL Med = 2.5 mL AI
Answer:
This is true because oxygen belongs to the non-metal part of the periodic table.
<span>96.09 g/mol, so weight of Oxygen in the whole thing is 16g/mol*3 = 48.
48/96.09 = around 49.95%</span>
