Answer:
As the amount of substances increases density will increase.
Explanation:
Density and mass have direct relation while density and volume has inverse relation. If the volume of substance is kept constant then the density of substance will increase with same factor as the mass of substance is increases.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
<span>Intermolecular Forces present in HCl:
The Electronegativity difference between Chlorine and Hydrogen is 0.96 showing that the bond is polar covalent in nature. The Hydrogen atom is partially positive and Chlorine is partially positive making the molecule Dipole. Hence, the Intermolecular forces present in HCl are Dipole-Dipole Interactions.
</span>Intermolecular Forces present in CH₄:
The Electronegativity difference between Chlorine and Hydrogen is 0.35 showing that the bond is non-polar covalent in nature. Hence, the Intermolecular forces present in CH₄ are London Dispersion Forces.
Answer: It has 13 electrons total and and 3 in the valance shell.
Explanation: Aluminum
Given: Molecular formula of the compound is C₈H₁₁O₂
Since C₈H₁₁O₂ molecule contains two atoms of oxygen which is equal to one mole.
∵ In 1 mole of C₈H₁₁O₂, oxygen has = 1.0 mole
∴ In 3.7 moles of C₈H₁₁O₂, oxygen has = (1.0 mole) × (3.7 moles) ÷ (1 mole)
= 3.7 moles
Hence, oxygen has 3.7 moles in 3.7 moles of C₈H₁₁O₂
