please show detailed explintion for both questions.

A solute was diluted 1:1000 and its present concentration is 60 ug/mL. What was the original concentration of the solute before the dilution? The technician made a 1:20 dilution of a 600 ug/mL glucose solution. What is the concentration of the prepared solution?

Solution

(1)

Concentration of present solution = 60 ug/mL

Dilution fold = 1000

Original concentration = Concentration of present solution x fold dilution

Original concentration=60 ug/mL x 1000

Original concentration=60000 ug/mL

Original concentration= 60 mg/mL

(2)

Concentration of present glucose solution = 600 ug/mL

Dilution fold = 20

Original concentration = Concentration of present solution x fold dilution

Original concentration=600 ug/mL x 20

Original concentration=12000 ug/mL

Original concentration=12 mg/mL
