Answer: 3500cm-1
Explanation: The -OH bond absorbs IR and vibrates at a characteristic and many times distinctive wave number of 3500cm-1. The -C=O would vibrate at 1700cm-1 though not clearly because -C-O bond typically vibrates around this point
2N2+3H2>2NH3, H2=2.02g/mol, N2=28.02g/mol
42.5(1/28.02)(2/2)(17.04)
