You are conducting a plant growth experiment and need to generate a solution with growth factor, auxin or indole-3-acetic acid. You need 100ml of 400mM indole-3-acetic acid for this experiment. How much indol-3-acetic acid (solid; MW=175.2 g/mol) should you add to generate your solution?

7,01 g of indole-3-acetic acid

Explanation:

The milimolar concentration (mM) is defined as the ratio of milimoles per Liter of solution. 400mM means 400mmoles / L that is the same of 0,4mol / L

100mL are 0,1L. Using these values:

0,1L × (0,4mol / L ) = 0,04moles of indole-3-acetic acid.

As the MW of the molecule is 175,2 g/mol:

0,04mol × (175,2g / mol) = 7,01 g of indole-3-acetic acid

Thus, you need 7,01 g of indole-3-acetic acid to generate your solution.

I hope it helps!
