Tungsten is the metal used in the filaments of incandescent light bulbs. Naturally occurring tungsten consists of five isotopes with the following isotopic masses and abundances:
Calculate the atomic mass of naturally occurring tungsten to five significant figures.
Each of the Isotopic mass * its Abundance Sum together divide by 100. (179.946706*0.12 + 181.948206*26.5 + 182.9502245*14.3 + 183.9509326*30.64 + 185.954362*28.43 ) / 100 You get 183.84 (5s.f. ) or (183.8417786) _award brainliest if helped!
To calculate the average atomic mass, multiply the mass of the isotope by its corresponding abundance: 179.946706 * .0012 + 181.948206 * .2650 + 182.9502245 * .1431 + 183.9509326 * .3064 + 185.954362 * .2843 = 183.84178 = 183.84
