Answer
0.025 ml
Solution
a
Given: The concentration of the DNA solution is 20mg/ml20 \, \mathrm{mg/ml}
b
Convert 500μg500 \, \mu g to mgmg: 500μg=0.5mg500 \, \mu g = 0.5 \, mg
c
Use the formula: Volume=MassConcentration\text{Volume} = \frac{\text{Mass}}{\text{Concentration}}
d
Substitute the values: Volume=0.5mg20mg/ml=0.025ml\text{Volume} = \frac{0.5 \, mg}{20 \, mg/ml} = 0.025 \, ml
Key Concept
Concentration and volume relationship
Explanation
To find the volume of a solution needed to obtain a specific mass of solute, you can use the formula Volume=MassConcentration\text{Volume} = \frac{\text{Mass}}{\text{Concentration}}. In this case, converting the mass from micrograms to milligrams and then applying the formula gives the required volume.
