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)

Sources of error: Method 1 Equipment:About ten grams of NaHCo3. 10 ml distilled waterSmall beaker Electronic balanceGlass dome10 ml graduated cylinderGlass rod Safety instructions :Wear safety goggles Wear a smockBe deilcate with materials Method:Measure out 10 ml of distilled water using the graduated cylinder. Transfer the water to the small beaker.Weigh out the total amount of sodium chloride available for the experiment.Weigh out 0.5 g NaHCo3. Add NaHCo3 to beaker containing water. Stir solution with glass rod until dissolved.Repeat step 3 until it becomes more difficult to dissolve the NaHCo3. Note the number of times 0.5 g NaHCo3 is added.Continue adding one grain of NaHCo3 at a time until it is no longer possible to dissolve it.Once saturation is reached, NaHCo3 crystals form at the bottom of the beaker.Measure the mass of NaHCo3 not added to determine the total amount of NaHCo3 that has exceeded the solubility limit.

A 1 mL microbial suspension comparable to 1 mL of 1.0 McFarland standard was subjected to a series of dilutions. An aliquot of 0.2 mL was transferred into a 100-mL volumetric flask and diluted with sterile saline solution to its final volume. Then a 0.1 mL of the resulting solution was transferred into a 50-mL volumetric flask diluted to its final volume. What would be the final concentration?
