What volume of H2O should be added to 500 ML of a 1.0 mol/L CuSO4 solution to dilute it to 0.5 mol/L? This is what I have so far... H20 + CuSO4 --------> H2SO4 + CuO So you use the formula M1V1 = M2V2 so its (0.500)(1.0) = (0.5)(V) Solve for V, I got 1.0 L. HOWEVER, the ...

Use the dilution relationship (Mi x Vi = Mf x Vf) to calculate the volume of 0.500 M NaOH needed to prepare 500 mL of .250 M NaOH. This is my work ? L Solution = 500mL x (1L/1000mL) = .500L ? mol NaOH = .500 L Solution x (0.250 M NaOH/1 L Solution) = .125 mol NaOH ? L solution...

What are the units for crying out loud? Are all of them 100 mL. I will assume that is what you meant except for the dilution which I assume is 0.500 L or 500 mL. 14 g/100 = 0.14 g/mL You took 55 mL of that so you have in the aliquot of 55 mL exactly 0.14 g/mL x 55 mL = 7.70 g...

SURELY you have a typo. I don't know how you can dilute a 35.0 mL sample to 0.500 mL. You might dilute it to 0.500 L but not mL. I will assume you intended to write "A 35.0 mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100 mL of ...

Describe how you would make 250 mL of 0.500 M HCI
Using the dilution formula M1V1 = M2V2 you would use the following calculations. ((250 mL)x(0.500 M HCl))/12.1 M HCl = 10.3 mL This means you want to add 10.3 mL of the 12.1 M HCl into a 250-mL volumetric flask and then fill the rest with distilled water up to the etch line in...
