Calculate the vol. of 1.0M sucrose for 0.2M boiling tube.

= (0.2M)(20ml)/1.0M

= ?

• 2ml

• 4ml

• 6ml

• 8ml

• 10ml

Calculate the vol. of 1.0M sucrose for 0.3M boiling tube.

= (0.3M)(20ml)/1.0M

= ?

• 2ml

• 4ml

• 6ml

• 8ml

• 10ml

Calculate the vol. of 1.0M sucrose for 0.4M boiling tube.

= (0.4M)(20ml)/1.0M

= ?

• 2ml

• 4ml

• 6ml

• 8ml

From the table in the video, identify the molarity of sucrose Isotonic to the potato cell.

• 0.1M - 0.2M

• 0.2M - 0.3M

• 0.3M - 0.4M

• 0.4M - 0.5M

From the graph, the isotonic molarity is --- (the point where line graph cross the X-axis)

• 0.3M

• 0.31M

• 0.35M

• 0.4M
