WebAug 31, 2024 · Polyimide (PI) is a polymer of imide monomers containing two acyl groups bonded to nitrogen. It can be thermosetting as well as thermoplastic. It replaces materials like glass, metals and even steel in some applications. Known for its very high thermal stability (>500°C), it also exhibits excellent dielectric properties and inherently low ... WebApr 7, 2024 · 3. Divide the mass of the solute by the total mass of the solution. Set up your equation so the concentration C = mass of the solute/total mass of the solution. Plug in your values and solve the equation to find the concentration of your solution. [6] In our example, C = (10 g)/ (1,210 g) = 0.00826. 4.
