PLEASE HELP How many moles of helium gas are in a 30.0 L sample of He, if density of helium gas us 0.016 g/ml?

I think you need to use dimensional analysis with this problem as well, please help!!

I pray to god, that this helps you, cuz if not, then you know why i got a F in english and a D- in algebra :")

33.6 L (this is the answer i think- i'm not sure but i do have a link to the REAL answer- https://socratic.org/questions/what-would-be-the-volume-of-6-00-g-of-helium-gas-at-stp#629064  here are the steps- along with the answers)

.

Explanation:

= 33.6 L

Explanation:

(seriously though, please tell me this helped you)

o"w"o

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
