M=m/n chemistry. The ejection of the photoelectron from the silver metal in the photoelectric effect experiment can be stopped by applying the voltage of 035 V when the radiation 2567 nm is used. A solution with a concentration of 1 mol L is said to be 1 molar commonly designated as 1 M. Levine 5 th Ed Tata McGraw Hill Pub.

Atomic mass is particularly important when dealing with stoichiometry. M n. A solution with a concentration of 1 molL is said to be 1 molar commonly.

If m or n is zero the reaction is zero order in A or B respectively and the rate of the reaction is not affected by the concentration of that reactant.

Moles mass. Laidler 3 rd Ed. In chemistry concentration of a solution is often measured in molarity M which is the number of moles of solute per liter of solution.
