Please check my answers and if correct, provide me with the formulas for each answer

you can make zoom because I can't make better than this

Acetone is to be recovered from an aqueous waste stream by continuous distillation. The feed contains 5 mol of acetone (95 mol% of water). Acetone of at least 95 mol purity is wanted and the aqueous effluent must not contain more than 1 mol acetone. The feed will be a saturated liquid at 15.000 kg h Estimate the number of ideal stages required. (Given: Total Reflux ratio = 2 * minimum reflux ratio) X (mol fraction Acetone 01 02 0.3 0.4 0.5 0.6 0.7 08 09 liquid) Y(mol fraction Acetone 0.73 0.79 0.81 0.83 0.84 0.85 0.87 0.89 0.93 vapor) Determine following: q value for saturated liquid feed = 1 y intercept for minimum reflux = 0.7 reflux ratio = 0.72 y intercept for the total reflux ratio = 0.55 Number of stages from the graph = 10 Destillate flow rate (D) = 31.91 kmolh Bottom flow rate (B) = 718.08 kmol/h Vapor flowrate (V) in the colum = 54.89 kmolh Liquid flowrate (L) in the top section = 22.98 Liquid flowrate (L') in the bottom section = 772.98
