Here is the answer of the given question
Answer: Option B
Explanation:
Cell membrane can be defined as the outermost covering of the cell which allows the movement of particles across membrane. The particles are allowed to move from inside of the cell to the outside of the cell and from outside to inside of the cell.
This kind of a membrane is known as selectively permeable which allows the movement of certain molecules only.
hence, the correct answer is option B
Answer:
56.0 g
Explanation:
Calculation of the moles of
as:-
Mass = 85.0 g
Molar mass of
= 162.2 g/mol
The formula for the calculation of moles is shown below:
Thus,

According to the reaction:-

1 mole of
on reaction forms 1 mole of
Also,
0.52404 mole of
on reaction forms 0.52404 mole of
Moles of
= 0.52404 moles
Molar mass of
= 106.867 g/mol
Mass = Moles*Molar mass =
= 56.0 g
