For the following question please read carefully the question and instruction. If you do answer the question correctly with correct significant figure and post it in the next 20 minutes. I will write a wonderful and generous feedback/review/rating about you if you do as what I prescribed. Thank you very much. 

 

Given data - 

• equation of graph ???? = 44770x + 690.3
• The concentration fo NaCl in the chicken stock is 0.12 mol/L 

During an conductivity experiment you obtain theses values (image 1 and 2) below

 

 

The questions that you have to answer with correct significant figure and the correct answer is the following:

 

1. What is the sodium content (in g) of the entire bouillon cube?
2. The sodium content listed in the nutritional information for the bouillon cube is 1.600 g per cube. If we consider this to be the true sodium content, calculate the absolute error (in g) and the relative error (%) of the sodium content you determined experimentally.
