Dear friend Abdullah Al Mahmud

Oh, the thrilling world of nanoparticles and calculations! Let me unravel this puzzle for you with fiery enthusiasm.

To calculate the concentration of nanoparticles in grams, you must consider the weight percentage (wt%) of the nanoparticles you want to add to the polymer solution.

Step 1: Determine the Mass of Polymer Solution

Let's say you have 100 grams of the 10 wt% polymer solution. That means 10 grams of the solution are polymer, and the remaining 90 grams are the solvent or other components.

Step 2: Calculate the Mass of Nanoparticles

To add 3 wt% nanoparticles to the polymer solution:

3 wt% of 100 grams = 0.03 x 100 grams = 3 grams

So, you need to add 3 grams of nanoparticles to achieve 3 wt% concentration.

To add 5 wt% nanoparticles to the polymer solution:

5 wt% of 100 grams = 0.05 x 100 grams = 5 grams

You'll need to add 5 grams of nanoparticles to achieve 5 wt% concentration.

Step 3: Double Check

To verify your calculations, add the mass of the nanoparticles to the total mass of the solution and ensure it matches the desired final mass. For example, if you add 3 grams of nanoparticles to the 100-gram polymer solution, the final mass should be 103 grams.

Remember, my fiery friend Abdullah Al Mahmud, these calculations are based on the weight percentage of the nanoparticles and the initial mass of the polymer solution. Always double-check your numbers to achieve the desired concentration and rock those nanoparticle experiments with confidence!

Kaushik Shandilya Thank you very much brother for your generous answer.

The concentration of nanoparticles is respect to the Total polymer concentration

Say in this case the total concentration of the polymer is 10% you want to add 3% of nanoparticles of total Polymer concentration

3->100

X->10

X= (3x10)/100=0.3g of nanoparticles

Asmaa Sayed Thank you for your response.

Do you mean if my total polymer concentration of the solution is 10g?

@Abdullah Al Mahumud Yes 10g in 100ml (10wt%) Polymer
