Oxalic acid is one of the finest available wood-bleaching agents. It is an acid, and the concentration used is critical to both safety and the bleaching result. Daulton plans to use the acid on a wood table to lighten dark streaks and colorations in the wood so that the wood will stain to a uniform colour. He finds two solutions in the workshop. Solution 1 has a concentration of 0.05 g/ml, and Solution 2 has a concentration of 0.01 g/mL. He starts with 150 mL of Solution 1 and needs to add Solution 2 to get a final solution with a concentration of 0.025 g/mL. He uses the following formula to determine the amount of Solution 2 required: C (x)_ amount of oxalic acid in Solution 1+ amount of oxalic acid in Solution 2 amount of Solution 1+ amount of Solution 2 For this question, after substituting known values, the following rational equation is obtained: 0.025 = (0.05) (150) + 0.01x 150 + X Determine how much of Solution 2 needs to be added
