Explanation:
The given data is as follows.
= 10 mM =
M
= 750 ml,
= 5 ml
= ?
Therefore, calculate the molarity of given NaCl stock as follows.


= 1.5 M
Thus, we can conclude that molarity of given NaCl stock is 1.5 M.

Answer:: We're asked to find the molar concentration of the NaCl solution given some titration data.
Explanation:
Answer:
Moving them farther apart
Explanation:
One can try to change the distance between the two positive charges in such a way that it increases the distance and decreased the electric force.
Density is defined as the ratio of mass and volume. The formula of density is:
-(1)
Density of milk =
(given)
Volume of milk =
(given)
Substituting the values in formula (1):



Hence, the mass of the milk is
.
