For the following, use the relation of M1V1 = M2V2, where M represents the molarity of the solution, and V represents the volume: How would you prepare 100 ml of 0.5M solution using your stock solution? 4) How would you prepare 500 ml of 0.5 M solution using your stock solution?

Calculate the mass of dye (MW = 452.87 g/mol) needed to create 150 mL of a solution 5.55 * 10-3 М.

You are asked to prepare 100.0 mL of a 30.0% (m/v) NaCl solution.  The procedure states that 0.513 moles of NaCl are needed.  How many grams of NaCl should you mass out on the balance?

What is the concentration in molarity of a solution which is 11.39 %m/v octane (MM = 114.2 g/mol ) in hexane (MM = 86.18 g/mol)?

Chromium (III) chloride forms a hexahydrate, CrCl3*6H2O (s). How many grams of CrCl3*6H2O (s) are needed to prepare 250 milliliters of an aqueous solution that is .500 M in Cr3+ (aq)?

Discussion This virtual experiment involves the determination of the conc¬entration of salt (sodium chloride, NaCl) in an aqueous solution. Concentration may be expressed many ways, and this experiment studies two systems: molarity (M) and weight/volume percent (%w/v). 1. Molarity is defined as the number of moles of solute (in this case NaCl) in a liter of solution. It is calculated with the following equation: M = moles solute liters solution 2. Percent concentration (w/v) is defined as the number of grams of solute (in this case NaCl) in 100. mL of solution. It is calculated with the following equation: %(w/v) = grams solute x 100mL solution The experimental method involves taking a specific volume of an aqueous salt solution and slowly evaporating it to dryness. The weight which remains is that of the solute. From the weight of solute and the initial volume of solution, both molarity and percent (w/v) can be calculated. Experimental In this virtual experiment, three students (A, B…

Calculate the mass of dye (MW = 452.87 g/mol) needed to create 150 mL of a solution 5.55 * 10-3 М.

Calculate the volume of stock glucose solutions (2.5 % and 15%) that need to be used to prepare 800 mL of glucose solution with a concentration of 13%. In this case % refers to the grams of glucose per 100 mL of water. V1= volume of stock solution with concentration C (2.5%) V2= volume of stock solution with concentration C2 (15 %) You need to determine V, and V2 in mL
