Posted by smiley on Friday, August 31, 2007 at 12:24pm.

Please help me through this problem...
A 0.5117 gram fertilizer containing phsphorus was oven dried. The weight of the dried sample is 0.4998 grams. However, 10% moisture is still retained in the sample. Calculate the moisture content in the sample in as received and dry basis. If the sample is completely dried, how much wouldit weigh?

My work:
0.5117-0.4998 = 0.0119 grams -> amount of water removed excluding the 10% left in the sample...I don't know what to do next.
