Using NaH2PO4-2H2O instead of NaH2PO4. How to calculate?
Posted: Mon Jul 09, 2012 12:48 pm
I have a recipe that calls for 3.2g of NaH2PO4 (anhydrous). We have NaH2PO4-2H2O (dihydrate) in stock and I have been told I can use that after working out how much to use.
I know that the FW of the anhydrous is 119.98 and of the dihydrate it is 156.01.
BUT, how oh how do I work out how much of the dihydrate to use instead?
Any help or insight would be much appreciated.
