In the lesson, you saw how to perform three types of calculations related to solution concentration:
a. calculate molarity when given the components of the solution
b. calculate the amount of solute (in moles and grams) required to make a solution of a designated volume
c. calculate the volume of solution of a given molarity when the amount of solute is known
Now you will perform your own calculations. For each scenario below, list which calculation you are being asked to perform (a, b, or c from the list
above) and then solve the problem.
Part A
Suppose you wanted to make an aqueous solution of sodium hydroxide that is 1.8 M. You want to make 250 ml of the solution. How many grams
of sodium hydroxide are needed to make this solution? Note which type of calculation you need to perform, and then perform the calculation.

Ascientist wants to know how individual lions within a pride interact with each other in their own environment. to do this, the scientist sedates and tags all of the lions within a pride. then, he places several remotely-controlled video cameras near the lions' den and performs an observational field study. he collects continuous video footage over the span of one year, analyzes the video, and then forms conclusions based on his observations.
