The letter μ indicates 
The correct answer is that letter. (μ)
It is not in the options but it is correct.
To solve this we use the
equation,
M1V1 = M2V2
<span>where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.</span>
4.5 ( V1 ) = 3.0 ( 500 mL )
V1 = 333.33 mL needed of the 4.5 M phosphoric acid
Hope this answers the question. Have a nice day.
