How many milligrams of Erioglaucine (FD&C Blue #1) are required to make 150. mL of blue dye with a concentration of 25.0 mg/L?*Hint: dimensional analysis*

Answer :

SAMUELADESIDA43GO

3.75 milligrams of Erioglaucine are required to make 150. mL of blue dye with a concentration of 25.0 mg/L

HOW TO CALCULATE MASS:

  • The mass in milligrams of Erioglaucine can be calculated by multiplying the volume of the dye by its density as follows:

  • Mass (mg) = volume (L) × density (mg/L)

According to this question;

  1. The volume of the blue dye is 150. mL = 150/1000 = 0.150L
  2. The density of blue dye is 25.0mg/L

Mass = 0.150L × 25mg/L

Mass = 3.75mg

  • Therefore, 3.75 milligrams of Erioglaucine are required to make 150. mL of blue dye with a concentration of 25.0 mg/L
