Explanation Given: Mass of radium-226 gas = 25.00 g Atomic mass of radium-226 =226.025402 amu=226.025402 g/mol Half-life of radium-226 = 1.6 × 10 3 years . Time=5.0 days Temperature =25°C = 298 K Pressure = 1.0 atm Formula used: • Decay constant(λ) can be calculated using : λ= ln 2 t 1 / 2 • Amount of substance left after decay (N) can be calculated as: N = N 0 e − λt N 0 = Initial amount of substance t= time • According to ideal gas law , PV= nRT Where P= Pressure, V= volume, T= Temperature, n= number of moles and R- Gas constant Calculation: First calculate the decay constant: t 1 / 2 = 1.6 × 10 3 years = (1.6×10 3 ×365) days = 584 × 10 3 days λ= ln 2 t 1 / 2 = 0.693 584 × 10 3 d a y s = 1.186 × 10 − 6 d a y − 1 Now, the amount of Radium-226 left after decaying to radon-224 for 5...
