6.023 × individual carbon atoms are there in one mole of carbon.
Mass of a 1 atom= 12 amu
1 amu = 1.66 × gm
∴ 12 amu =1.99 × gm
∴Mass of a 1 atom=1.99 × gm
Mass of C in 1 mole = 12 gm
∴Total number of atoms of carbons in 1 mole = 12 ÷ 1.99 ×
∴Total number of atoms of carbons in 1 mole= 6.023 × atoms
6.023 × individual carbon atoms are there in one mole of carbon.
The number 6.023 × is known as Avogadro's number, which represents the number of individual atoms present in a one mole of substance with respect to atoms.

Static Friction, Sliding Friction, Rolling Friction, and finally Fluid Friction.
Texture extrusive rocks dry very fast so they are typically small and jagged on the outside
Answer:
336.8 kilo Joules is the change in internal energy of the system.
Explanation:
The equation for first law of thermodynamics follows:
where,
Q = heat added to the system
ΔU = Change in internal energy
W = work done
We have :
Amount of heat given out by the system will be negatuive as heat relased by the system = Q
Q=
Work done on the system will positive as work is done on the system:
w =
336.8 kilo Joules is the change in internal energy of the system.
Answer : The concentration of ion is, 0.00371 M
Explanation :
First we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Now we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Thus, the concentration of ion is, 0.00371 M
