The concentration of the new solution 0.71 M
Given:
initial volume of solution = 25 ml
concentration of solution = 2.3 m
volume of solution after dilution = 80 ml
To Find:
concentration of solution after dilution
Solution:
Molarity is define as moles of solute present in 1000 ml of solution. It's unit is given by mol/L or M. Here molarity is given by the formula
M1V1 = M2V2
M2 = (V1/V2)*M1
M2 = 25/80*2.3 = 0.71 M
So, molarity of solution after dilution is 0.71 M

Cooks should use sea salt in recipes instead of regular table salt.
The transfer of hydrogen to the ETC is made possible because of coenzymes made from b vitamins. An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+) across a membrane.
