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.

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?

Describe in detail how you would make a series of four standards ranging from 1 to 100 ppm given the following constraints. a. Your stock solution is 1000 ppm. b. The available pipets have volumes of 2.00 mL, 3.00 mL, and 5.00 mL. c. The available volumetric flasks have volumes of 10.00 mL, 25.00 mL, 50.00 mL, and 100.00 mL. d. You need to make at least 10.00 mL of each of your four standards.
