I have a quiz yall help

How many moles are in a 18 L tank of nitrogen gas at STP?

12

Explanation:

i feel like its 12 because moles are medium sized but are they adult moles or baby moles or growing moles

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
