I presume you want to know the molar quantity of 3xx10^-3*L3×103L at "STP"STP.

Explanation:

It is well known that at "STP"STP 11 molmol of Ideal Gas will occupy a volume of 22.4*L22.4L. (This will even be given as supplementary material in most examinations)

Thus "Moles of helium"Moles of helium == (3xx10^-3*cancelL)/(22.4*cancelL*mol^-1) = ??*mol
