Cedrick and Astrid a 20.00 ml aliquot of grapefruit juice with a 0.165 M NaOH solution to the end point. The initail buret reading was 1.72ml and final buret reading was 15.51ml. They calculated that there was 0.1457g of citric acid present in the juice sample. What is the amount mg of citric acid present per ml of juice? the answer is 7.29mg/ml. (can you please show me how to calculate this answer)
