Blood alcohol content is a measure of alcohol in the blood as a percentage. It is calculated in grams per 100 mL of blood, so a BAC of 0.08 means your blood is 0.08% alcohol by volume.
what is the total mass of alcohol (in grams) that is present for the same adult male whose total blood volume is 5.6L?
Fluoridation is the process of adding fluorine compounds to the drinking water. Fluoridated water can help decrease tooth decay in the population. A concentration of 1 ppm of fluorine is typically required to provide adequate amounts. While daily water consumption per person is 151.0 gallons, most people only consume 7.6 of this water; the rest is used for cleaning or gardening. What percent of the sodium fluoride is “wasted”?
A chemistry student must write down in her lab notebook the concentration of a solution of potassium chloride. The concentration of a solution
equals the mass of what's dissolved divided by the total volume of the solution.
Here's how the student prepared the solution:
• The label on the graduated cylinder says:
empty weight: 1.55 g
• She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed
31.436 g.
• She added water to the graduated cylinder and dissolved the potassium chloride completely. Then she read the total volume of the solution
from the markings on the graduated cylinder. The total volume of the solution was 166.4 mL.
What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits.
