You need to make an aqueous solution of 0.220 M copper(II) nitrate for an experiment in lab, using a 500 mL volumetric flask. How much solid copper(II) nitrate should you add? ______________grams
Calculate the following quantity: volume of 1.184 M copper(II) nitrate that must be diluted with water to prepare 204.6 mL of a 0.5422 M solution.
2. Assume you start with a 2.00 g sample of copper (II) nitrate. a. How many moles of copper (II) nitrate do you start with? b. Your sample will undergo multiple steps, each of which has the potential for loss of product. Assuming a percent yield of only 65.0 %, how many moles of copper (II) sulfate would you expect to produce? c. If the product is now dissolved in water inside of a 50-mL volumetric flask (as in the...
A. In some cases, multiple-step dilutions are required during sample preparation. Consider a case in which 50μL of concentrated dye solution was first diluted to 250mL with distilled water. From this resulting solution, 600μL was transferred to a 100mL volumetric flask and diluted with water to the mark. Calculate the dilution multiplication factor that will be needed to be applied before reporting the concentration in the original solution. Show your calculations. B. Occasionally, the volume of a sample must be...

A 3.7514 g sample of copper(II) nitrate is dissolved in water and 2.000 g of copper(II) arsenate (Ksp = 7.6 x 10-36) is added so that the total solution volume is exactly 1 L. What is the concentration of the arsenate ion in the solution (assuming the arsenate ion does not react with water)? (b) If the arsenate ion does react with water, write the overall principal chemical equation and determine K. (Arsenic acid is triprotic: Ka1 5.8 x 10–3...
Calculating molarity using solute moles Kirste A chemist prepares a solution of copper(II) fluoride (CuF) by measuring out 0.205 umol of copper(II) fluoride into a 300 ml volumetric flask and filling the ask to the mark with water.
