Lab 1 Osmosis and Diffusion Pre Lab

Lib IAP Biology: Pre-Lab for Osmosis & Diffusion Name_

The purpose of this assignment is to help you think through the procedure thoroughly so that you understandwhat you are to do and have an opportunity to think about predictions based on the principles you alreadyknow. You will make a sketch of each set-up and label it excessively so that, without using any real narrative,you have a complete picture representation of your lab procedure for each part. Don't worry about your skillat drawing---just include all the detail you can! Then make a prediction about what will happen in each part.

Show calculations with proper units throughout!

Define molarity.

Describe in detail how to make one liter of a 1M solution of an y solute.

How would you change that procedure to make one liter of a .5 M solution?

How would you change that procedure to make 500m1 of a .25 M solution?

What is the molar mass in grams of sucrose? Show your work!

Calculate the amount of sucrose in grams needed to make the following:

solute: sucrose solution volume: one liter solution volume: 500 mll.0 M

0.8 M
