How do you prepare M Cal solution?
To prepare 1 M CaI aqueous solution, dissolve 29.4 g in a total volume of 100 mls, or 294 g in a total volume of 1 liter.
What is the mass percent of the solution. if An aqueous NaCl solution is made using 138 g of NaCl diluted to a total solution volume of 1.10 L Assume a density of 1.08 g per ml for the solution.?
138 g NaCl 1.10 L= 1100mL 1100mL x 1.08g/mL = 1188 grams TOTAL 138/1188 x 100 = 11.6%
If 0.93 mL of a 0.127 M HCl solution is diluted with water to a total volume of 10.00 mL what is the resulting concentration in M?
The resulting concentration in M is 0,0118 (approx. 0,012).
The molecular mass of glucose C6H12O6 is 180 g To make a 0.5 M solution of glucose you should do what?
Dissolve 90 g of glucose in a small volume of water, and then add more water until the total volume of the solution is 1 L.
Why does the volume of sugar solution remain same but the weight increases?
The volume of the resulting solution is actually increased. As a rule of thumb the extra volume is about 60% of the kg mass taken in litres.Example: 1 L water + 1 kg sugar will take 1 L + 0.60L = 1.6 L(with total mass of 2 kg solution)

When 20 milliliters of 1 M HCL is diluted to a total volume of 60 milliliters the concentration of the resulting solution is?
.33
What happens to the concentration as the solution is diluted?
When a given solution is diluted, it concentration is usually lowered as well. The density of the given solution also changes when the solution is diluted.

How can you express the solution in percent by volume?
Per cent by volume means mls of solute per 100 mls solution. So you need to know the volume of the solute and the total volume of the solution. Divide volume of solute by volume of solution and multiply by 100 to get per cent by volume.
What are the mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume-The density of water is 1.00g per mL and that of ethanol is 0.789 grams per mL?
The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.
How much 2M Nacl solution would you need to make 250ml of 0.15M Nacl solution?
By the definition of molarity, which is mass of solute in moles divided by solution volume in liters, 250 ml of 0.15 M NaCl* solution requires (250/1000)(0.15) or 0.0375 moles of NaCl. Each liter of 2M NaCl solution contains 2 moles of NaCl. Therefore, an amount of 0.0375 moles of NaCl is contained in (0.0375/2) liters, or about 18.75 ml of the 2M NaCl, and if this volume of the more concentrated solution is diluted to a total volume of 250 ml, a 0.15 M solution will be obtained. _________________ *Note correct capitalization of the formula.
What quantities are compared when the concentration of a solution is measured?
In science, concentration is the number of moles of solute divided by the total volume of the solution (not just the volume of the solvent). Concentration units can also include the percentage solute to the total mass of the solution; the parts per million, ppm of the solute compared to the total parts present.
What is the percentage of volume?
Volume percent (v/v %) is defined as: volume percent = [(volume of solute) / (volume of solution)] x 100% Volume percent is handy when preparing solutions of liquids. Concentration of a solution can be stated in volume percentages. Be aware that volume of solution is in formula denominator, not volume of solvent. Thus to get 10% v/v solution of ethanol in water you can take 10 ml of ethanol and add enough water to have total 100 ml of resulting solution. It is worth to mention volumes of solute and solvent cannot be simply added to get volume of solution. For instance if you add 10 ml of ethanol to 90 ml of water the volume of the solution will be less than 100 ml.
How do you dilute a concentrated solution?
It really depends on what type of solution you are dealing with. However by definition any solution that is less pure or takes up a smaller perecentage of the whole is diluted. Anything that will make the total amount of solution you currently have become a smaller percentage of the whole. Ex: When you begin with solution A and have 100 mL it is 100%. If you mix in 100mL of solution B the total solution is now 200mL and it is 50% solution A and solution B. It is now diluted.
