You are asked to double check the calculations for the % soda ash (Molar mass = 105.99 g/mol) in your sample. You have calculated the [NaOH] to be 0.10012 M anc the [HCI] to be 0.1007 M. Your lab partner prepared the soda ash sample by adding 2.352 g of unknown into 748.0 mL of distilled water. You prepared the sample by adding 28.0 mL of soda ash, 55.0 mL distilled water, 4 drops of phenolphthalein indicator and you filled the burette with HCI. The initial reading of the burette was 0.56 mL. The pink solution turned colourless at 21.92 mL and your lab partner note down the volume of 43.81 mL for the second inflection point. Looking at the following set up below, how many errors are present from the information present above? [(0.1012 M) x (0.4325 L) x (1/2) (105.99 g/mol)]| 07 a 4 -T 100%
