Q2. (a) In order to analyze a sample of hydrated oxalic acid, the Bollowing data was collected :0.9g of anhydrous oxalic acid and 0.36g of water were present. Hydrated
Oxali acid has this formula (2001), XH 20.
©). Calculate the mole of anhydrous oxalic acid.
n. H2O4) = m (C2H2O4)

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
