Answer 1

Answer #1

According to given data:

A cylinder contain,

Volume(V) = 12.6 L , Pressure(P) = 41.4psi, and Temperature(T) = (25 + 273)K = 298 K P = 41.4psi = 41.4 * 0.068atm = 2.8152atm

According to ideal gas:

PI n = RT

n = 2.8152atm * 12.6L 0,0821atm. L.mol-.K-298K 35.47 24.46

n = 1.45mol
