A solution containing a trace amount of chloroform (30 mg/L) is to be reduced to 28 ug/L of CCl₄ using activated charcoal as the adsorbent. The Freundlich equation that applies to this system is y = k C ⁿ where C is in mg adsorbate/ L solution after processing, and y is the cumulative mg of adsorbate/ g adsorbent. K = 100 and n = 0.30 at the temperature of the process. How much activated charcoal in grams is required to treat 21 L of solution? Answer in whole number.
