A wound dressing containing silver nanoparticles (AgNPs) is applied to a wound. If the silver nanoparticles release ions at a rate of 0.5 mg/day and the total mass of AgNPs in the dressing is 10 mg, how many days will the dressing be effective in releasing silver ions?
|
20 days |
|
The answer can be found by dividing 10mg by 0.5
|
As the silver nanoparticles release ions at a rate of 0.5 mg/day, it would take 20 days for the 10 mg dressing to no longer be effective in releasing silver ions.

|
50 hours |
|
In order to find how long the hydrogel will take, you just need to divide the total work by the rate.

A zinc oxide nanoparticle (ZnO NP) solution has a concentration of 0.5 g/L. If you have 2 liters of this solution, how many grams of ZnO NPs are present in the solution?
|
1.0g |
|
As ZnO NP has a concentration of 0.5g/L, 1.0 g of ZnO NP will be present in 2 liters of the solution.
|
The answer can be gotten by multiplying 0.5 by 2.
