AI Thread Summary
To find the concentration of a solution, one must understand that it measures the amount of solute in a given volume. In this case, dissolving 3.576 grams of KCl in water and adjusting the volume to 200 mL allows for concentration calculations. The number of moles of KCl can be determined from its mass, which is essential for calculating molarity. Molarity is expressed as moles of solute per liter of solution. Understanding these concepts enables accurate concentration calculations.

we desolve 3.576 gr of KCL in water
and complement the volume to 200ml
what is the concentration of the solution??

Do you understand what concentration actually is? It measures the amount of ssomething in some volume. You could measure it in moles per litre, grams per mL etc. Think about what it means and see if you can try to solve it yourself.
 
i know how to calculate the number of moles in 3.576 gr of KCL
but i don't know what's the volume of that in the solution?

i could calculate the number of moles per litter

Good! Then you can calculate Molarity, which is moles of solute in 1 liter of solution.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
