Question

If 3.27 g of CuNO_3 is dissolved in water to make a 0.300 M solution, what is the volume of the solution? How many grams of sodium hydroxide are present in 249.0 ml of a 0.300 M NaOH? You need to prepare 250. ml of a 0.400 M aqueous solution of sucrose. C_12H_22O_11(aq). which is used frequently in biological experiments. Which type of glassware should you use to make this solution (assuming that the accuracy of the concentration is important)? How should the correct amount of solute be obtained? Measure out x mol of solid sucrose on a molemeter. Measure out x cm of sucrose with a ruler. Measure out x g of solid sucrose on a balance. Now that you have selected the correct unit above, what is the value of x? How should the solute and solvent be mixed in the container? Fill the container with water to the 250-mL mark, then add the solute. Add the solute, then fill the container to the 250-mL mark with water. Mix a small amount of water with the solute to dissolve it. then fill with water to the 250-mL mark.

Explanation / Answer

If 3.27 g CuNo3 is dissolved in water to make a 0.300 M solution

3.27 g x 1 mol/126 g = 0.025952381 moles
0.0259 mol /x L = 0.300 M

x = 0.086 liters = 86 ml s volume of solution--------------------answer

how should the correct amount be obtained?
measure out x gas of solid sucrose on a balance ------answer
