The following is a two groups (Regular tomato sauce & Salt Reduced Tomato Sauce) of data recorded by a team analysising salt content in tomato sauce using the MOHR titration method:
Regular Tomato Sauce
Salt Reduced Tomato Sauce
340.0mmol/L
262.7mmol/L
QUESTION: For both groups (Regular & Salt Reduced tomato sauce) of data provide answers to the following calculations below:
1. Standard Deviation (Sx)
2. T Values (t0.05,4)
3. 95% Confidence Interval (mmol/L)
4. [Na+] (mg/100 mL)
5. 95% Confidence Interval (mg/100 mL)
If we have leucine (2-amino-4-methylpentanoic acid), alanine (2-aminopropanoic acid) and phenylalanine (2-amino-3-phenylpropanoic acid), indicate the tripeptides that can be formed (use the abbreviated symbols Leu., Ala and Phe).
Briefly state why trifluoroacetic acid is more acidic than acetic acid.
