Tungsten undergoes first order decay to yield its isotope, with all reaction components in gaseous
form. The initial concentration is 1.00 M and the rate constant at 45 degrees Celcius is 6.94 x 10
6/minute.
(27a) What is the final concentration of the reactant remaining after 120 days?
Type-in your answer inblank#1. The unit is Molarity but enter only the value of your answer in normal
numerals (without symbols of unit and no digit or space fillers) with four significant figures.
(276) Calculate the percentage amount of the original reactant that has decomposed from the above
decay. Type-in your answer in Blank #2. The unit is % but enter only the value of your answer in
normal numerals (without symbols of unit) with four significant figures.
