(Please show step bys step process.) In paper recycling, scrap papers are torn and immersed completely in water. The solution, which is 20% dry scrap paper, is let undisturbed for about 8-12 hours and then blended (this becomes the paper pulp). Eight grams of starch is added for every 92g of pulp to help the pulp hold together better as it dries into paper later on. Arter addition of starch, the solution was dried such that the final solution will only contain 3% water. Calculate how many grams of the dry paper needed to make 100g of nearly dry paper.
