The density in kg/m³ = 1.14 x 10⁴
<h3>Further explanation </h3>Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density , g/cm³ or kg/m³
m = mass , g or kg
v = volume , cm³ or m³
A density of Lead : ρ = 11.4 g/cm³
the density in kg/m³ :
Answer:
The most acidic Protons are 4 or 5 .
Explanation:
The four types of hydrogen with numbering are shown in the given figure.
In order that a proton is acidic the conjugate base formed by removal of protons must be stable.
In case of given Hexane-2,4-dione molecule , the stability will be due to resonance. If we abstract a proton from the third carbon (between the two carbonyl carbons) it will result in formation of a carbanion, which is stabilized by resonance. The near by oxygen will give stability to the conjugate base by -I effect (negative inductive effect).
