How many moles are in 325 ml ne at stp?

Hey there!

325 mL in liters:

325 / 1000 => 0.325 L

1 mole ( Ne ) 22.4 L ( at STP )

moles ( Ne ) 0.325 L

moles Ne = 0.325 * 1 / 22.4

moles Ne = 0.325 / 22.4

moles Ne = 0.0145 moles

hope this helps!

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answer is d. 74.02
