1. The problem statement, all variables and given/known data A partially dried clay mineral contains 8% of water, the original sample contained 12% water and 45% silica. Then, the percentage of silica in the partially dried sample is nearly? 2. Relevant equations Don't know if this is would help in the calculation, in the original sample, 12% water is present, hence non water components are consisting of 88% 3. The attempt at a solution Attempted one but was out of range of the concept to be used.
