2. Calculate the total volume of water and of 0.4949 M NH, solution needed to create 25.0 mL of 0.100 M NH3 solution. Also calculate the total volume of water and of 0.2487 M H,SO, solution needed to create 25.0 mL of 0.100 MH,SO, solution. Note: you will be using these volumes for your lab, so keep the graduated cylinders available in Beyond Labz in mind for your final answers.

Hello! I am preparing for a lab in which I must carry out serial dilutions of quinine sulfate in a multi-well plate. I start with 200 microlitres of 100 ppm quinine sulfate in well A1. Using a handheld microlitre pipettor and the 100 ppm stock solution, I need to prepare standard stock solutions of quinine sulfate in wells B1-G1 with concentrations 50, 10, 5, 1, 0.5, 0.1 ppm. The final volumes must all be the same. I am completely clueless...

Using Atomic Absorption I wanted to measure how much copper was in a vitamin. The total vitamin when ground weighed 0.9687 grams. I dissolved 0.1049 grams in a 100 mL volumetric flask and measured how much copper was in that sample. It said there was 2.448 mg/L of copper in the sample. What was the total amount of copper in the vitamin?

How do you find the initial concentration if you are only
given the initial volume and final volume? I have tried using the
V(i) x C(i) =V(f) x C(f) equation but it needs at least 3 figures
so I'm a bit lost right now.
