Answer:
91.5 mol
Explanation:
Volume of gas = 70 L
Temperature = 25°C
Pressure = 32 atm
Moles of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
25+273.15 = 298.15 K
By putting values,
32 atm × 70 L = n ×0.0821 atm.L /mol.K × 298.15 K
2240 atm.L = n ×24.48 atm.L /mol
n = 2240 atm.L / 24.48 atm.L /mol
n = 91.5 mol
PV = nRT
I only know the valeu of R is you're using atm, so convert kPa to atm.
1 atm = 101.325 kPa
2.52 atm = 255 kPa
2.52atm(x) = 7(.0821)(342)
2.52atm(x) = 196.5
x = 78
78 liters
Answer:
37.1mL
Explanation:
This is a simple dilution problem where you utilize the equation:
(C=Concentration, V=Volume)
C1V1=C2V2
10.6(y)=0.715x0.550 (Y is unknown because we are trying to find how much of the original solution we need to dilute to make the final solution)
The solve for y and you get
y= 0.0317 L but this is in L and we want mL so multiply by 1000 you get
y= 37.1mL
