In this section, the rate of hydrogen formation is expressed as the molar rate of hydrogen production per mass unit of catalyst, denoted with ṅm and measured in µmol/h-gcat, which is micromoles of hydrogen production per hour per gram catalyst. In the case study, 43 photocatalysts ...
Determine the formula weight (molecular mass) of the given common acid. Calculate the molar mass of CaCI_2. What is the difference between molecular weight and exact mass? Calculate the molar mass of sulfamic acid which has the molecular formula of NH_2SO_3H....

Since the properties of HA derivatives are strongly influenced by the degree of substitution (DS), the knowledge of exact DS values is greatly needed. A very effective, reliable and widespread method for determination of DS of polysaccharides is 1H NMR spectroscopy. The area below the signals in...
