Acetic acid or vinegar is a weak acid.  The store bottles are 5% acetic acid by volume.  What volume of this solution will give you 15mL of the acetic acid?

A chemist must dilute 21.1mL of 6.81M aqueous calcium bromide CaBr2 solution until the concentration falls to 2.00M. He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in milliliters. Round your answer to 3 significant digits.

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H₂O). -6 Note: "major" chemical species are those present in concentrations greater than 10 compound sucrose fructose magnesium sulfate formula C₁2H22011 C6H₁2O6 MgSO4 major species present when dissolved in water U 7 X mol/L.

You are a work study student in our chemistry department. Amy, your supervisor has just asked you to prepare 100ml of 2.50M HClO4 solution for tomorrow's undergraduate experiment. The Stock Solutions cabinet is under the Stockroom Explorer. You will find find a 2.50 liter bottle containing 15M HClO4. Please prepare a flask containing 100ml of a 2.50M solution. To ensure proper credit, please write your calculations in the space given below.

In this task, you are to prepare 3 × 100 mL solutions of acetic acid at 3 different concentrations. You are provided with a stock solution at 2 % and will need to perform 3 dilutions. Complete the table below to calculate how much of the stock solution and how much water is required to prepare these solutions. For this calculation the following equation may be useful: C₁ V₁ = C₂ V2 Where C₁ is the initial concentration of the stock solution, V₁ is the amount of stock solution you need to add, C2 is the final concentration that you desire and, V2 is the final volume that you desire. All the values for this equation have been provided, aside from V₁ which you will need to solve the equation to determine. + Solution 2 Acetic acid at 0.5 % Solution 3-Acetic acid at 0.2% Solution 4 - Acetic acid at 0.1% Amount of stock solution to add A student uses the 1% acetic acid stock solution to make a new dilution for an experiment. The student takes 32 mL of the stock solution and makes a dilution…

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O). 9- Note: "major" chemical species are those present in concentrations greater than 10 major species present when dissolved in water compound formula ロロ fructose H. magnesium sulfate *osân nitrous oxide O'N Ex anation Check O 2022 McGraw Hill LLC.
