Hey dear,
● Gold number -
- It is defined as the minimum amount of protective colloid in milligrams which prevents a colour change from red to violet of 10ml gold sol by the addition of 1 ml of 10%NaCl solution.
● Answer -
x = 0.3 mg
● Solution -
Let amount of Hb required be x.
Here, gold number is calculated by -
Gold number = x × 10 / 100
x = 10 × gold number
x = 10 × 0.03
x = 0.3 mg
Therefore, 0.3 mg of hemoglobin will be required.
Hope this helps you...
