The dose of a strong cough medicine might be which of the following? 2mL, 200mL, 2L
Margarita [4]
To find the answer,we can picture how much the above value is by objects in real life.

2mL = about two drops of water

200mL = about a carton of milk/ a box of ornage juice

2L = 2000 × 10 mL = 20000 mL = The bottle of drinks that are in family/party size.

As we only take in small dosages of medicine, the best option would be 2mL.

Hope it helps!
