Synthesis include mol block

[MJCliffe]

Would be good to have a moles column in the synthesis information section to make stoichiometry clearer. This could connect with molar mass information down the line too.

We discussed at some point adding a products section to the synthesis procedure (and I guess we can bake in multistep reactants/products much better with individual steps), but for now you can specify a unit of mol in the synthesis information right? We just don't use anything useful with it... Definitely this is something we should discuss/improve with a few of us (related issue: #442)

[MJCliffe]

I think we want both the mass and the moles: the mass is what we actually measure and the moles are what we impute.

A product box would be nice too: I guess it needs to be clear what goes in it rather than the box.

If there were a box where we can put in chemical formulae and then the moles could be directly calculated.

Some of this depends on the design of this section of course!

[MJCliffe]

Is there any update on this? Basically every prep we have to input both mass and mol so it would be very convenient to have the mol automatically determined from the mass input.

No update, but lets get back onto this. The "difficulty" (i.e. boring technical difficulty rather than data modelling) is that we would want to compute the mols on the server rather than have any scientific stuff in JS, and getting that to happen without a page refresh would be a bit inelegant (would need a separate API route for just moles/mass conversion... not the end of the world!)

Let me extend our data model for constituents to be essentially (substance, amount, unit, molarity), with [amount + unit] computed if molarity is provided, and vice versa, then see how interactive we can make it.
