My approach was to set the waters of hydration to 2, and then set this equal to the moles of water over the moles of hydrate as this is the way I would find the number of waters of hydration given that I knew the masses. I know the molecular weight of the anhydrous and hydrate, but I don't know the gram amount for either. How can I find the number of moles of water here? At first I tried determining the percentage of the molar mass which water was relative to the anhydrous product and then multi... 1 mole = molar mass (could be atomic mass from periodic table or molecular mass) 1 mole = 22.4 L of a gas at STP (You do not need to worry about this yet) ... Mole Calculation Worksheet - Answer Key What are the molecular weights of the following compounds? 1) NaOH 22.99 + 16.00 + 1.01 = 40.00 grams/mol 2) H 3 PO 4 I was doing some ideal gas law and relative molecular mass questions but I was unsure about the units. Using the density formula, I got to M (around 0.00641) but I was unsure about the units. I knew I had to multiply by 1000 to get to g mol\^-1 but what are the units before you multiply by 1000? Did I ask a stupid question? Edit: wow, didn't expect this to blow up like this, ty all for your explanations, this is much clearer now. I didn't get why we would use a unit that describes a quantity when we already have a quantity related unit that is the mass, especially when we know how to weight things. Thank you again for your help, I really didn't expect the reddit community to be so supportive.

I am writing an article about Rubisco affinity to its substrates CO2 and O2. Rubisco is an enzyme with quite complicated working mechanism. Firstly, it covalently bounds to the RuBP, forming RuBP enediolate. I believe that i can simulate this docking with AutoDock flexible side chain method, but I'm not entirely sure, because binding mechanism is, in a way, complex. Then, enediolate of the RuBP binds with either carbon dioxide or oxygen. This process is too quite complex. The best way would b...
