Answer:
The new concentration of the sample is m₂ = 0.025X
Step-by-step explanation:
The relation between previous concentration and new concentration of the sample is given by
m₁v₁ = m₂v₂
Where m denotes the concentration and v denotes the volume in liters.
Re-arranging the above equation for m₂ yields,
m₂ = (m₁v₁)/v₂
Substitute the given values
m₁ = 50X
v₁ = 10 μL = 10×10⁻⁶ L
v₂ = 20 mL = 20×10⁻³ L
So the new concentration is
m₂ = (m₁v₁)/v₂
m₂ = (50X*10×10⁻⁶)/20×10⁻³
m₂ = 0.025X
Therefore, the new concentration of the sample is 0.025X
