8. Jorge is working in a lab. The lead scientist has asked him to make up a
solution containing 350 milligrams of dextrose. However, the scale only
weighs in grams. How many grams of dextrose should Jorge put in the
solution?
0.35 grams
9. Susan has been told she needs to take 3 grams of a drug everyday. Her pills
only come in 250 milligram sizes. How many pills should she take every
day?
12 pills
Solve the pH problems
1. The pH of rainwater is about 5.6. Is rainwater acidic, basic, or
neutral? neutral
2. The pH of a Coke is 2. What is the hydrogen ion concentration of the
solution? .01
3. What is the hydroxide ion concentration of Coke (pH 2)? 10 -12
4. Solution A has a pH of 3, and solution B has a pH of 5. This means solution A
is more acidic than solution B. This also means that solution A
has more hydrogen ions than solution B.
5. Solution A has a pH of 12 and solution B has a pH of 7. This means solution A
is more basic than solution B. This also means that solution A
has fewer hydrogen ions than solution B.
6. You are creating a tank to grow tadpoles in for an experiment. You know that
tadpoles prefer a relatively neutral pH. Over time the water is likely to
become more acidic due to tadpole excretions and other biological processes.
