How Do You Calculate the Formula for Hydrated MgSO4 Using Experimental Data?

AI Thread Summary
To calculate the formula for hydrated MgSO4 using experimental data, first determine the moles of MgSO4 by dividing the mass (2.25g) by its molar mass (141.46 g/mol), resulting in 0.016 moles. The difference in weight between the starting material and the product indicates the mass of water lost during hydration. This mass loss is essential for determining the number of water molecules associated with each formula unit of MgSO4. Use the ratio of moles of water to moles of MgSO4 to establish the final formula for the hydrated compound. Understanding these calculations is crucial for accurately determining the hydration state of MgSO4.

i used 2.25g x 1 mole/141.46 = 0.016 moles



The Attempt at a Solution


i'm not sure how to calculate the formula. how do i do that? is there a different equation involved?
please reply, i really need help.

assume that your product is pure MgSO4. You know the mass and FW. Calculate moles. The difference in wt betwieen starting material and product represents what?
 

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...
