Pre You would like to determine which of two substances is more likely to easily diffuse
across a semipermeable membrane based on molecular weight. You have calculated
the molecular weight of carbon dioxide (CO2) as 44,
Choosing the appropriate information from below (which would normally be found in
a Periodic Table), calculate the molecular weight of lactose (C12H22011).
bC12
THA
B016
The molecular weight of lactose is 34
The molecule that is more easily going to diffuse is lactose, due to its lower molecular
weight
Answer 1:
34
Answer 2:
lactose
Answer 3
