Answer:

102.26 moles of helium were required to Fill the Goodyear Blimp

Explanation:

To solve this question we need to use combined gas law:

PV = nRT

<em>Where P is pressure, V is volume of gas (2500L), n are moles of gas (Our incognite), R is gas constant (0.082atmL/molK) and T is absolute temperature</em>

<em />

Assuming atmospheric condition we can write P = 1atm and T = 25°C = 298.15K

Replacing:

PV/RT = n

1atm*2500L / 0.082atmL/molK*298.15K = n

<h3>102.26 moles of helium were required to Fill the Goodyear Blimp</h3>

The volume of a sample of nitrogen is 6.00 liters at 35oC and 0.75 atm. What volume will it occupy at STP?
joja [24]
The  volume that  will  occupy  at STP  is  calculated   as  follows
by use  of ideal  gas  equation
that is  PV=nRT  where n  is  number of  moles  calculate  number of moles

n= PV/RT
p=0.75 atm
V=6.0  L
R = 0.0821  L.atm/k.mol
T=  35  +273= 308k
n=?

n=  (o.75  atm  x  6.0 L)/( 0.0821 L.atm/k.mol  x 308 k)=  0.178 moles

Agt  STP  1 mole=  22.4 L  what obout  0.178 moles

=  22.4  x0.178moles/ 1moles =3.98 L( answer C)
