Sugar is easily soluble in water and has a molar mass of 342.30 g/mol. What is the molar concentration of a 245.6 mL aqueous solution prepared with 78.3 g of sugar? Suppose you have 350.0 mL of a 0.450 M sodium hydroxide solution. How many moles of sodium hydroxide are in the solution? Calculate the percent by mass of a solution made from 17 g NaCl (the solute) and 67 g water. Suppose you need to prepare 141.5 mL of...
A) A chemist prepares a solution by adding 304 mg of Co(NO3)2 (MW = 182.94 g/mol) to a volumetric flask, and then adding water until the total volume of the contents of the flask reaches the calibration line that indicates 100 mL. Determine the molarity of the prepared solution. B) Determine the mass of chloride (MW = 35.45 g/mol) in grams present in 100mL of a 0.289 M solution of aqueous FeCl3 (iron(III) chloride). C) A beaker contains 250 mL...
A solution is prepared by dissolving 200.0 g of iron (III) chloride (162.2 g/mol) in 200.0 mL of water. What is the molarity of the solution?
Question 4 Status: Not yet answered | Points possible: 1.00 Glucose (molar mass 180.16 g/mol) is a simple, soluble sugar. Glucose solutions are used to treat patients with low blood sugar. Suppose you prepare a glucose solution using the described procedure. Step 1: Dissolve 294.4 g of glucose in enough water to make 500.0 mL of solution. Step 2: Transfer 18.6 mL of the solution to a new flask and add enough water to make 250.0 mL of dilute solution....
