How much of a 0.2M stock solution of NaCl would you need to make a 100mL dilution of NaCl at final concentration 0.05M? Please give your answer in units of MILLILITERS, however do not explicitly include any units in your answer. If you include units in your answer, your answer will be scored as being incorrect.

Suppose you add 34 grams of sucrose (table sugar) to a glass of water having a volume of 160 mL. If I tell you the formula weight for sucrose is 342.3 grams per mole (g/mol), what is the concentration of this solution in Molarity? Note: It is understood that the unit will be Molar (mol/liter). However, do not include any units in the answer. Instead, type in the numerical value only. Adding anything other than the numerical value will result in your answer being counted wrong.
