V (volume) = 5l
c (molar concentration or molarity) = 3 M = 1 mol/l
c = n/V, where n is the number of moles or amount of substance
So: n = c * V = 3 mol/l * 5l = 15 moles
<h3>In general,the more massive a star is,the shorter it's life span on the main sequence.After the hydrogen fuel at the core has been consumed,the star evolves away from the main sequence on the HR diagram,into a supergiant,red giant,or directly to a white dwarf.</h3>
