<h3>Further explanation</h3>
Given
1000 C of charge for x grams of copper
Required
Number of charge
Solution
Faraday's Law :

For 1000 C, W = x grams

For 5x grams :

Answer:
an isotope has the same number of protons but a different number of neutrons than the other atoms of the same element.
Explanation:
It is known that molarity is the number of moles present in a liter of solution.
Molarity = 
Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.
No. of moles = 
= 
= 0.025 mol
Therefore, calculate the molarity as follows.
Molarity = 
=
= 0.025 M
Thus, we can conclude that molarity of
in milk is 0.025 M.
