A student would like to prepare a 0.010 M solution from a 1.0 M stock solution with minimal error. The student can choose to do a one-step dilution that uses a 10 mL transfer pipet and a 1000 mL volumetric flask or a two-step dilution using a 50 mL pipet and a 1000 mL volumetric flask for the first dilution, and a 100 mL pipet and a 500 mL volumetric flask for the second dilution. Which method has the smallest overall relative uncertainty and what is the value? **Use table 4.2 on page 70 in your textbook for tolerances of the glassware. O One-step dilution; 0.0020 Two-step dilution; 0.0020 O Two-step dilution; 0.0014 O One-step dilution; 0.0010

A series of iron standard solutions need to be made from a 40 ppm iron stock solution provided. For the first dilution, pipet 5.00 mL of the 40 ppm stock solution into a 100.00 mL volumetric flask and dilute to mark. What is the new concentration of the diluted solution?
Please help me with this one Sugar is the solute and water is the solvent. The drink mix will be considered negligible and is added simply for the visualization of dilution results. Calculate the concentration of sugar in this solution using the volume percent equation. Refer to the background for sample calculations. For the purpose of this exercise, it can be assumed that the weight of the drink mix is 0.00 g. The volume of the solution is 3 and 1/3 cups. Convert to metric units, then calculate and record the volume percent in Data Table 1 (Note that 1 cup = 236 mL). Volume % = Volume of Solute/ Volume of Solution × 100%
Starting from the primary standard solution in Question 4 and using the dilution scheme in Figure 1, calculate the concentrations of Standards #1-5. Show all work on a piece of scratch paper. Label each calculation clearly (Standard #1, Standard #2, etc) and circle your final answer for each standard. Be sure to round your answers to the correct number of significant figures and include units. Molarity in #4 is 0.0004089 M or 4.089x10^-4

A chemistry student is given 1.00 L of a clear aqueous solution at 17 degrees Celsius. He is told an unknown amount of a certain compound X is dissolved in the solution. The student allows the solution to cool to 17 degrees Celsius. The solution remains clear. He then evaporates all of the water under vacuum. A precipitate remains. The student washes, dries and weighs the precipitate. It weighs 0.12 kg. Using only the information above, can you calculate the solubility of X in water at 17° C? If you said yes, calculate it and be sure your answer has a unit symbol and 2 significant digits.
