5.367 ml of the concentrated acid must be added to obtain a total volume of 100 ml of the dilute solution.
Dilution is defined as the process in which the concentration of a sample is decreased by adding more solvent. The dilution formula is given below.
C₁V₁ = C₂V₂
where C₁ = initial concentration of sample = 3.00 m
V₁ = initial volume of sample
C₂ = final concentration after dilution = 0.161 m
V₂ = total final volume after dilution = 100 ml
Plug in the values to the formula and solve for the volume of the concentrated acid that must be added.
C₁V₁ = C₂V₂
3.00 m (V₁) = 0.161 m (100 ml)
V₁ = 5.367 ml

Answer:
7 μl /s
Explanation:
Given data:
0.44 mL/min
μl /s = ?
Solution:
First of all we will convert the mL/min to mL/s.
we will divide the given value by 60.
0.44/60
0.007 mL/s
Now we will convert the mL/s to μl /s.
we will multiply the value with 1000.
0.007 × 1000
7 μl /s
