To calculate the moles of AgNO3 in a solution, we need to know the volume and concentration of the solution.
Moles of AgNO3 = Volume of AgNO3 solution (L) * concentration of AgNO3 solution (M or mole/L) = 1.50 L * 0.050 M = 0.075 mole.
So 0.075 moles of AgNO3 are present in 1.50 L of a 0.050 M solution.
Using Ideal Gas Laws :
PV = nRT
Where,
P is Pressure = Not given
V is the Volume = 56L
n is number of moles of gas = Not given
R is the proportionality constant = 0.08206 L.atm/K.mol
T is the temperature = 25 + 273.15 = 298 K
Step 1:
Calculate n,
n = 2 x 15.999 = 31.998 g/mole
n (oxygen) = 64/31.998
= 2 moles of oxygen
Step 2:
Calculate Pressure,
P = nRT/V
Substitute the values,
P = 2 x 0.08206 x 298/56
P = 0.88 atm
