having a problem defining what mol% means

SunriseSunset - 25-9-2015 at 14:36

Reaction conditions: reagentA (1.0 mmol), reagentB (3.0 mmol), K3PO4 ·3H2O (3
equiv), CuI (10 mol %) in DMSO at 110 °C for 20 h.

If the molar mass of reagentA was 150g / mol
And the molar mass of reagentB was 100g / mol

How much of the catalyst CuI (10 mol%) in DMSO should be used for this reaction? :(

And what does the K3PO4 ·3H2O (3
equiv) mean?

Ten mol % CuI means that you add 0.1 mol CuI as a catalyst for every 1.0 mol of reagent A. 3 equiv. means that you add 3 mol potassium phosphate trihydrate for every 1 mol of reagent A.

What, pray tell, is reagent A that has a molar mass of 1.5 g/mol? H1.5?

No lol it isn't H1.5 :\
However, this was very helpful thank you!

Please try to find things before bleating.
