What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
The total volume of the solution is 48 mL + 144 mL = 192 mL. The percent by volume of ethanol is calculated as (volume of ethanol / total volume of solution) * 100%. Plugging in the values, we get (48 mL / 192 mL) * 100% = 25%. So, the solution contains 25% ethanol by volume.
A solution contains 30 g of calcium chloride in 250 g of water express the mass percent?
The solution has a total mass of 30 + 250 = 380 g. The mass percent of calcium chloride in this solution is 100(30/380) = 7.9 %, to the justified number of significant digits.
What is the percent mv of a water solution that contains 60 g of calcium chloride CaCl2 and that has a volume of 400 mL?
To calculate the percent mass/volume (m/v) of the solution, you would divide the mass of the solute (CaCl2) by the volume of the solution and then multiply by 100. In this case, the mass of CaCl2 is 60 g and the volume of the solution is 400 mL. So, the percent m/v would be (60g/400mL) x 100 = 15% m/v.
A chemist has one solution that is 80 percent acid and another solution that is 30 percent acid How much of the first 80 percent solution is needed to make a 400 L solution that is 62 percent acid?
To create a 400 L solution that is 62% acid, you would need 200 L of the 80% acid solution and 200 L of the 30% acid solution. This would result in a final solution with the desired concentration.
Are Sodium Chloride 0.9 percent and Normal Saline the same solution?
Yes, Sodium Chloride 0.9% and Normal Saline are the same solution. Normal Saline is a sterile solution of 0.9% sodium chloride in water, commonly used in medical settings for hydration and to dilute medications.
1 percent solution of a medication equals how many micrograms?
A 1 percent solution of a medication means it contains 1 gram of the medication in 100 mL of solution. To convert grams to micrograms, you multiply by 1,000,000. Therefore, a 1 percent solution would contain 1,000,000 micrograms of the medication.
What is the concentration as percent of a solution which contains 160 g of solute in 2.75L of solution?
The answer is 5,82 %.
What solution contains the largest volume of solvent in 100mL?
A solution with the highest concentration of solute will contain the largest volume of solvent in 100mL. This means a dilute solution with a low amount of solute will have the highest volume of solvent remaining.
A balloon permeable to water but not to glucose contains a 10 percent glucose solution A beaker contains a 5 percent glucose solution the solution in the balloon is what?
The balloon will contain a mixture of the 10% and 5% glucose solutions. Since water can pass through but not glucose, the glucose concentration inside the balloon will decrease over time as water moves from the lower concentration in the beaker to the higher concentration in the balloon through osmosis.
If a 10 percent sugar solution is separated from 20 percent sugar solution by a selectively permeable membrane in which direction will there be net movement?
The direction will be towards the more concentrated side so the 10% solution with go towards the 20% solution in an attempt to reach equilibrium.
What are the components of a 5 percent Sodium Chloride solution?
This solution contain 5 g NaCl dissolved in water.
What has a percent by volume of 0.038?
A solution with a percent by volume of 0.038 contains 0.038 liters of solute dissolved in 100 liters of solution. This means that 0.038% of the total volume is the solute.
How many grams of a 0.90 percent mmNaCl solution contain 0.450g of NaCl?
50 g
How many percent of oxygen does air contain?
Air typically contains about 21% oxygen by volume.
What is the weight of 10 percent acetic acid?
The weight of 10 percent acetic acid solution would depend on the total volume of the solution. For example, if you have 100 grams of a 10 percent acetic acid solution, it would contain 10 grams of acetic acid.
Why does ten percent salt solution diffuse faster than one percent salt solution?
A ten percent salt solution diffuses faster than a one percent salt solution primarily due to its higher concentration gradient. The greater difference in concentration between the salt solution and the surrounding solvent drives the movement of water molecules and solute ions more rapidly. Additionally, the increased number of solute particles in the ten percent solution creates a higher osmotic pressure, facilitating faster diffusion as the system strives to reach equilibrium.
How much glucose is in one liter of 5 percent dextrose in water?
A 5 percent dextrose solution contains 5 grams of dextrose (glucose) per 100 milliliters of solution. Therefore, in one liter (1000 milliliters) of a 5 percent dextrose solution, there would be 50 grams of glucose.
