# Homework Help: Finding mass of glucose in standard solutions

1. The problem statement, all variables and given/known data

This is for an experiment that separates sugars in a sample using TLC.
We are given a glucose standard solution with a concentration of 1mg/ml as well as 3 standard sugar solutions (glucose, fructose and maltose) all with the same concentration (10mg/ml) in 10% v/v isopropanol)

We are asked to find μg of glucose (reducing sugar) in each of the standards.

2. Relevant equations
I don't think there are any equations, just conversions.

3. The attempt at a solution
Convert the mg/ml to μg/ml or to μg/μl
But I'm not sure if I'm overthinking it or if it's the way the question is worded because it's worth only 1 mark.

Hard to say anything not knowing how the question is worded. From your description it can be anything and everything.

We're given a juice sample and we use thin layer chromatography to identify the sugars in there. They gave us the concentrations of the standard sugar solutions and we were asked to find the μg of glucose (the reducing sugar) in each of the standards. They said to refer to the glucose concentration given to us which was 1 mg/ml. The concentration of the standards were 10 mg/ml though.

From what you wrote there is no glucose in the other standard solutions.
