Answer:
In my opinion, I think its 2
Explanation:
Molar mass Na = 23g/mol
46g = 456/2 = 2mol
1mol = 6.022*10^23 atoms
2mol = 2*6.022*10623
= 1.204*10^24 atoms
Answer:
Explanation:
When there is difference between the concentration of the content of a cell and the solution surrounding the cell, there will be an Electrochemical gradient or Concentration gradient. Therefore, some solute will tend to move from the region of high concentration to the region of lower concentration through the cell membrane.
Such a movement is called Primary Active Transport
Limitations of Van der waal's equation. (i) The value of 'b' is not constant but varies with pressure and temperature. (ii) The value of is not equal to 3b, but actually it is equal to, in some case; and in other cases 2b. (iii) The value of is not equal to but it is usually more than 3 for most of the gases.
233.1g
Explanation:
Given:
Formula units of FeCl₃ = 8.65 x 10²³ formula units
Unknown:
Mass of the FeCl₃ = ?
Solution:
The formula unit is the same as the amount of subatomic particles in an atom.
1 mole of a substance = 6.02 x 10²³ formula units
For 8.65 x 10²³ formula units; the number of moles;
Number of moles = 
= 1.44moles
Now to find the mass of FeCl₃;
Mass of FeCl₃ = 1.44 x 162.2 = 233.1g
