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

<h3><u>Answer;</u></h3>
= 3.064 g/L
<h3><u>Explanation;</u></h3>
Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
Number of moles is 1 since one mole has a mass equivalent to the molar mass.
Therefore; We can find the volume and thus get the density.
V = nRT/P
= (1 × 0.08206 × 498 )/ 0.939
= 43.52 L
But; density = mass/volume
Therefore;
Density = 133.34 / 43.52
= 3.064 g/L
You have a. 3, b. 2, e. 6, f. 3, i. 1
This is cyclopentane looks like. Each corner represents carbon atom. Since there are five corners, hence it is called cyclopentane. All the carbons are sp3 hybridized. Hope this helps.
