Answer:
Some positive effects of using synthetic plastic is that scientist can make it softer and biodegradable so that nature can break it down and destroy it so it won't affect the environment. And scientist can also make stronger and tougher in products so they can last longer.
Explanation:
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.
