What is the mass of the solution in grams? c. What is the volume of the solution (in mL)? d. Calculate the mass/volume% of the solution. e. Calculate the molarity of the solution. f. If you diluted 25 mL of this solution to a volume of 100 mL, what would...
1. A 50.0-mL pipette sample of a liquid is found to weigh 120.71 g. a. What would be the mass of 32.25 mL of the same alcohol? b. What volume would be occupied by 25.4 g of this alcohol?
Calculate the volume percent of solute in the following solutions. 28.1 mL of methyl alcohol in enough water to give 495 mL of solution. 66 7 mL of ethylene glycol in enough water to give 229 mL of solution.
Question 15 1 pts A bottle of cold medicine contains 25% (v/v) ethyl alcohol (ethanol) in water. . In 125 mL of medicine, how much ethyl alcohol is there (in mL)? Ethyl alcohol is C2H60 and has a density of 0.789 g/mL. What is the molarity of the solution? . Question 16 1 pts If you make a solution by using 45 g glucose (C6H12O) and add enough water to make 250.mL of solution: . What is the % (m/v)...
Isopropyl alcohol is mixed with water to produce a 38.0% (v/v) alcohol solution. How many milliliters of each component are present in 875 mL of this solution? Assume that volumes are additive. alcohol: mL water: ml The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 695 mL of a 38.0% (w/v)...
The BAC is usually expressed as a percent based on weight/volume. This means that the BAC is the grams (g) of alcohol present per 100 mL of blood. For example, a BAC of 0.12% is equivalent to 0.12 g alcohol per 100 mL of blood. At 0.12%, most people are intoxicated! Typically 100 mL is referred to as 1 deciliter or 1 dL. So, 0.12% is also equivalent to 0.12 g/dL. The BAC can be calculated based on how much...
calculate the amount of NaCL and water needed to prepare 50.0 mL of a 1.85% (by mass) NaCl solution. Assume that the added salt does not change the volume of the water.
