Determination of Riboflavin in Foods by Fluorescence

Your experimental data are:

The recommended daily allowance $($RDA$)$ for riboflavin is $1\mathrm{.}35m\frac{g}{?}$ day.

The $\%$ RDA per serving of the food product is $25\%.$

The serving size of the food product is $32g.$

The amount of food product weighed for the extraction is $3\mathrm{.}5874(g{)}_{?}.$

Wavelength of Maximum UV Absorbance: $450nm.$

Operational Excitation Wavelength: $432nm.$

Operational Emission Wavelength: $526(nm{)}_{?}.$

Fluorescence Emission of the Solutions:

You have completed the laboratory portion of this lab.

The questions below are part of the final analysis, they are due $30$ minutes prior to the beginning of the next lab, Thu Apr $1812$:$45$:$00$ pm $2024($EDT$).$

Based on your experimental data, enter the linear regression of the appropriate calibration curve:

$y=758x+317$

You are correct.

Your receipt no$.$ is $158-7198(7)$ Previous Tries

Using that linear regression, calculate the concentration of riboflavin in the analyzed solution:

$$pb

Tries $\frac{0}{3}$

Using dilution factors correctly and assuming $100\%$ extraction, calculate the amount $()$ of riboflavin in the $3\mathrm{.}5874g$ of food product sample that you weighed.

$g$

Tries $\frac{0}{3}$

Use your data to calculate the amount $(mg)$ of Riboflavin in one complete serving of food product.

$mg$

Tries $\frac{0}{3}$

Determine the $\%$ error between the label value for riboflavin per serving of food product $(mg)$ and the amount of riboflavin per serving that you calculated for the food product
