1- a- How do you prepare 600 mL 4 N H2SO4 solution using 50% Sulfuric acid stock solution (d: 1.403 g/mL MW:98g/mole)? b- If you took 10 mL from this sulfuric acid solution (4N) and diluted to 1000 mL, what would be the % (w/v) and ppm concentration of the final solution.
You wish to prepare 100 mL (total volume) of a buffer solution that is 0.025 M in carbonic acid, pH 7.25. You have solid H2CO3 and solid NaHCO3. Calculate how many grams of H2CO3 and HCO3- you need to weigh out to prepare this solution.
describe quantitatively and qualitatively how you would prepare 1000. mL of a 2.00 M solution of nitric acid from a 18.0 M H2SO4 stock solution
calculate the concentration of sulfuric acid if 8.0 mL of 18.0 M H2SO4 is diluted to 600 mL
A 11.4 mL sample of 0.180 M sulfuric acid (H2SO4) is titrated with 0.250 M NaOH Calculate the volume, in milliliters, of NaOH solution that will be used.
Calculate the molarity of an H2SO4 solution if 20 mL of 0.50 M NaOH exactly neutralizes 40 mL of the H2SO4 solution.
You wish to prepare 100 mL of a buffer solution that is 0.025 M in carbonic acid (H2CO3). The pKa of H2CO3 is 6.351. Calculate the amount of H2CO3, in grams, that you will need to weigh out.
Density of a 3.75 M sulfuric acid (H2SO4) solution is 1.23 g/ml. Calculate its mass %, XH2SO4, molality & normality.
Your cell-preparation protocol calls for you to prepare EXACTLY 1000 mL of dilute room temperature phosphate buffer solution. You use boiling water to quickly dissolve your phosphate salt. You carefully measure out exactly 1000 mL of this solution when it is still at 55∘C. Once the buffer solution has cooled to room temperature (20∘C), how much more or less volume solution do you actually have? (Be careful with your signs! Remember that a positive difference will be an increase in...
