Answer:
The volume of gas is 3.26 L.
Explanation:
Given data:
Pressure = P = 5.91 atm
Temperature = T= 66.1 °C = 66.1 +273.15 = 339.25 K
Number of moles of oxygen gas= n = 0.691 mol
Volume = V = ?
Formula:
PV = nRT
R is general gas constant and its value is 0.0821 dm³.atm.K⁻¹.mol⁻¹ .
Now we will put the values in equation.
V = nRT/ P
V = ( 0.691 mol× 0.0821 dm³.atm.K⁻¹.mol⁻¹ × 339.25 K) / 5.91 atm
V = 19.25 dm³. atm/ 5.91 atm
V = 3.26 dm³
or
V = 3.26 L (dm³= L)
