Asalt crystal has a mass of 0.18 mg . how many nacl formula units does it contain?

Afuel composed, by weight, of 70% carbon, 28% hydrogen, and 2% sulfur is burned with 10% excess air  for an 800 mwe plant with a 40% thermal efficiency:  what is the input fuel requirement ?  what are the emissions ? perform all the calculations (for example, the heating value and the fuel input mass flow rate) exclusively using si units (i.e., kj/kg and kg/hr), and (2) do not divide and conquer, rather use the single long stoichiometric balance equation and explicitly calculate the number of moles of the reactants and products to determine the flue gas emissions in kg/hr. (you do not have to compute the scrubber system input/output masses.)
