Volume of a substance can be determined by dividing mass of the substance by its density.
That can be mathematical shown as:
Density=Mass/Volume
So, Volume=Mass/Density
Here mass of the substance given as 24.60 g
Whereas density of the substance is 2.70 g/mL
So,
Volume=Mass/Density
=24.6/2.7
=9.1 mL
So volume of the substance is 9.1 mL.
Answer: 5.44×10226.022140857(74)×1023⋅mol−1.
Explanation: So the answer is approx. 0.10⋅mol
Answer:
d. dispersion forces
Explanation:
Dispersion forces -
It is a very weak type of interaction observed between two atoms , when the electrons of the respective atoms attain a position where they form temporary dipoles , is referred to as dispersion forces.
These are the temporary force of attraction.
These force of attraction are also referred to as induced dipole-induced dipole attraction .
These force of attraction are possible when the electrons are unsymmetrically distributed thereby induces positive and negative poles.
Similarly ,
Stearate ion and oil drop have dispersion force between them.
Answer:
The two variables affecting the rate of diffusion are the concentration gradient and size of the molecule. Concentration gradient: The movement of the substance is generally along the concentration gradient of the solute and it moves from a region of its higher concentration to a region of its lower concentration.
