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)
Answer:
17.8ml-15.6ml is 2.2 ml then convert to cm so 2.2cm^3
The number of animal balloons created in 15 minutes = 20
The number of animal balloons created in 1 minute = 
So, the number of animal balloons created in 6 minutes = 
And, the number of animal balloons created in 45 minutes = 
So, the solved ratio table will be:



Answer:
The gases will expand until a volume of Vf= 10812 cm^3
Explanation:
Since the gas mixture is expanding at constant pressure

and therefore

knowing that 1 torr=133,32 Pa

therefore
