For hospital patients suffering from dehydration, it may be necessary to provide them with intravenous fluids. A common IV bag used for this purpose contains 4.00% (wv) glucose (MW = 180.16 g/mole) and 0.450% (w/v) of sodium chloride (MW = 58.44 g/mole). If you were attempting to prepare a standard 1.00 L bag of this solution starting from a stock solution containing 30.0% (w/v) glucose and 3.38% (w/v) sodium chloride, how many mL of the stock solution would you need? Hint: Only one calculation is needed.

What volume (in mL) of 30.0% hydrogen peroxide solution is required to provide the mass required in question 8 above? Mass=10.2g of a 30% hydrogen peroxide soltuion. Density of 30.0% H2O2 = 1.11 g/mL Answer with 3 sig figs.

Please help I'm not sure how to solve these.  A solution is prepared by dissolving 20g of NaCl (f.w.= 58.44 g mol^-1), a nonvolatile solute, in enough water (m.w. = 18.02 g mol^-1) to result in exactly 1 L of solution at 25 C. The density of the solution is 1 g mL ^-1.   How do you calculate freezing point of the solution as well as vapor pressure and the osmotic pressure? I understand boiling point.

Potassium permanganate solution (BI) Prepare 100.0 mL of ~0.00100 M KMnO4 solution from the 0.02XXX M KMnO4 stock solution. Record the exact molarity of the stock solution. Take about 20 mL of the stock solution in a small beaker to your bench. Using the appropriately sized volumetric pipet, transfer the required amount of stock solution from the beaker to the 100.0 mL volumetric flask. Fill it to the mark with distilled water, stopper it and invert several times to mix the solution. Volume of KMnO4 Stock Solution added via pipet Calculate Molarity of solution BI

The solution is in steps on paper

Calculate the volume of stock glucose solutions (2.5 % and 15%) that need to be used to prepare 800 mL of glucose solution with a concentration of 13%. In this case % refers to the grams of glucose per 100 mL of water. V1= volume of stock solution with concentration C (2.5%) V2= volume of stock solution with concentration C2 (15 %) You need to determine V, and V2 in mL

For this question it’s telling me use KCI which stands for potassium chloride so do I use KCl, (1 atom X 39.0983 Potassium) + (1 atom X 35.453 Chlorine) = (74.5513 g/mol) and use that with 10 ML of 20% Solution. I’ve been stuck on figuring out what I could do for this question. I want a long clarification and steps on it so it could help me know if I’m correct as I’m doing this question on my notebook.

A 2.00 mL aliquot of reagent grade HCl was diluted to 250.0 mL. The diluted solution was standardized using sodium carbonate, and the concentration of the prepared solution was determined to be 0.09606 M HCl. What is the concentration of reagent HCl (in %w/w)? Note: the specific gravity of the reagent HCl was 1.18 g/mL.
