The amount of phenol in a liquid sample was analyzed using GC-MS with 4-methoxyphenol as internal standard. 2.0 ml 3.0 g/l standard phenol solution and 1.0 ml 3.0 g/l standard 4- methoxyphenol solution in a 100.0 ml volumetric flask, diluting up to the mark using ethanol. What is the concentration of phenol in the original liquid sample (g/l)? a) 0.78 g/l b) 0.95 g/l c) 3.52 g/l d) 4.16 g/l
Accepted Answer
This problem requires calculations involving GC-MS analysis and internal standards, which are chemistry-related concepts. To solve this, we need more information about the peak areas or ratios obtained from the GC-MS analysis. Please provide those values, and I can help you calculate the concentration of phenol in the original sample.
