Chapter 1, Problem 1.79E

A)  Calculate the molarity 12.21 mg KI in 107.6 mL of solution         Express your answer using four significant figures.   B) A chemist wants to make 6.0 L of a 0.310 MCaCl2 solution. What mass of CaCl2 (in g) should the chemist use?         Express your answer in grams using two significant figures.

Compare the slope in the picture with the literature value of 11,100 liter • mol-1 • cm-1. You will have to convert the slope in the picture to have the same units as the literature value. Clearly show how this unit conversion is done

Does it make a difference if you use a volumetric flask vs a beaker vs a graduated cylinder to make a solution?

(The ? stands for a number the student is going to calculate.) Fill in the missing part of this equation. Note: your answer should be in the form of one or more fractions multiplied together. (-5.1 x 10' Pa cm' 3 3 = ? kPa·m x10

A chemistry student weighs out 0.105 g of sulfurous acid (H, SO,), a diprotic acid, into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1300M NAOH solution. olo Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits. Ar mL ?

mol aqueous A chemist must prepare 675. mL of 195. mM aqueous aluminum sulfate (Al, (SO,) ) working solution. He'll do this by pouring out some 0.889 aluminum sulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the aluminum sulfate stock solution that the chemist should pour out. Round your answer to 3 significant digits.

Objective KTIO A chemistry student weighs out 0.0434 g of sulfurous acid (H,SO,), a diprotic acid, into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1800M NAOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Round your answer to 3 significant digits. mt. I Don't Know Submit 2022 McGraw Hill LLC. All Rights Reserved. Terms of Use Privacy Center Accessibility Launcher Lenovo

An aqueous solution of sodium chloride,NaCl , is made by dissolving 1.01 grams of sodium chloride in sufficient water in a 50.0 mL volumetric flask, and then adding enough water to fill the flask to the mark. What is the weight/volume percentage of sodium chloride in the solution? Weight/volume percentage =           %

A chemist must prepare 850. ml. of 10.0 mM aqueous potassium permanganate (KMnO,) working solution. She'll do this by pouring out some 13.0 mM aqueous potassium permanganate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in ml. of the potassium permanganate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits. D X 5
