Title: concentration calculation problem
Post by: jvm208 on January 28, 2019, 03:08:57 AM

Hi, can you please help with calculating the final concentration in mg/kg?

Concentration of product (as per on the label) = 550 mg/kg (it's a wettable powder product)
Chemical = dicamba
Weight of sample weighed = 1g
Final Volume = 200mL
Diluent = Acetonitrile

What would be the final concentration in mg/kg?

Thank you.

You can safely assume that density of your solution = density of acetonitrile.
