The number of moles of NaCl is 1.31 moles. This can be calculated by using the molarity formula i.e. M=n/V.
Molarity:
Molarity is defined as the ratio of the number of moles of solute to the Volume of solution in liters.
It is given by:
M = n/V
What information do we have?
Volume = 5.25 L
Molarity = 0.25 M
To find:
Moles=?
On substituting the values:
M=n/V
0.25 M =n/ 5.25 L
n= 0.25M*5.25 L
n=1.31 moles
Thus, the number of moles of NaCl are 1.31 moles.
