This app has been a lifesaver. I have recently started a position as an Administrative Assistant and the abilities within this program make my job hassle-free. It makes filling in PDFs and requesting e-signatures as efficient as possible.

****** from PdfFiller is Excellent!I needed to cancel my service for the time being for financial reasons and they handled it kindly and seamlessly with no hassle. Should I need this type of service again, I will definitely be back. Would recommend PdfFIller to others. The service itself is intuitive and helped me easily provide my on boarding information for my new job.

The software was actually really great and extremely useful. I didnt really experience any difficulties with it and was exactly what I needed and a quick pinch without having to install anything. There was one small issue with my account, but the support team got back to me within the same hour and resolved what I needed. Amazing all the way through.

How do you find the percentage of a mixture?
Mass percent is a method of expressing the concentration of a substance in a mixture or element in a compound. It is calculated as the mass of the component divided by the total mass of the mixture and then multiplied by 100 to get the percent.
How do you find the initial concentration of a reaction mixture?
Weigh the amount of solute (the compound being dissolved) in grams. Then determine how many grams are in a mole of the solute. Measure the amount of the solvent that you have. Divide the moles of solute found in Step 1 by the liters of solvent found in Step 2 to find the initial concentration of a solution.
