Question

how many moles are in 500ml of he gas at stp

Answer 1

.0223 moles

Answer 2

@rman3 can you explain how you got that answer instead.

Answer 3

Use PV=nrt, the ideal gas law.
P=Pressure v=volume in liters n=moles r=gas constant(.0821) = t=temp in K.
n=PV/RT
n=(1)(.5)/(.0821)(273)
n=.0223

Answer 4

Many ways to do a problem man

Answer 5

\(\huge NO\)

Answer 6

YEAH

Answer 7

since the gas is at STP, you can use this formula.....
\[n = \frac{ V }{ V_M }\]
n=no. of moles
V=Volume
V(M)=Molar volume (volume occupied by one mole of a gas at STP ) and this equals
24dm^3 = 24L
