The atomic mass of chromium is 52. The amount of chromium is 52/204 which is 25.5% of the total atomic mass of strontium chromate. Multiplying 100 pounds by the 0.255 yields 25.5 pounds of chromium. The 25.5 pounds divided by 2,000 pounds/ton is equal to .013 tons of chromium with the CAS number 7440473 as the reported pollutant code.
