Question

how do I calculate how many moles are in 10 ml of hydrogen gas?

Answer 1

at RTP or STP?

Answer 2

im not sure im doing a lab and it says calculate the moles of hydrogen gas collected and I collected 10 ml of it

Answer 3

Probably RTP if you did it in lab.

Answer 4

I remember the equation is PV=nRT, but that's about it.

Answer 5

you are solving for n, the number of moles. Plug in your pressure, etc. and solve for n.
Should look like \[\frac{ PV }{ RT } =n\]

Answer 6

yeah most probably its RTP so your RTP volume is \(\sf24~dm^3\)
and the formula you can use to find mole of H is
\(\sf your~volume = mole \times RTP~volume\)
your volume of H = 10mL
mole = X
RTP volume = \(\sf24~dm^3\)
so we need to find mole, thats why we gotta make mole of this formula as subject of this formula
\[\sf mole = \frac{ your ~volume }{ RTP~volume }\]
so use the formula and get the answer
