[QUOTE="Karol, post: 4958402, member: 20512"] [h2]Homework Statement [/h2] Into a 56[liter] container oxigen is filled in with manometric pressure of 4[atm] and temp' 47[SUP]0[/SUP]C. what is the mass. Then a leak happens and the pressure drops to 3.5[atm] and temp' 27[SUP]0[/SUP]C. How much oxigen escaped. [h2]Homework Equations[/h2] $$PV=nRT$$ $$R\left[\frac{liter\cdot atm'}{mole\cdot ^0K}\right]=0.08208$$ Atomic number O[SUB]2[/SUB]=16 [h2]The Attempt at a Solution[/h2] The initial conditions: ##3[atm]\cdot 56[liter]=n\cdot 0.08208\cdot 320^0K\rightarrow n=6.4[mole]## $$m=6.4\cdot 16=102.3[gr]$$ Second stage: $$\frac{P_1V_1}{n_1T_1}=\frac{P_2V_2}{n_2T_2}\rightarrow\frac{P_1V_1}{m_1T_1}=\frac{P_2V_2}{m_2T_2}$$ Our volume is fixed, so: ##\frac{3}{102.3\cdot 320}=\frac{2.5}{m_2\cdot 300}\rightarrow m_2=90.97[gr]## Is it correct?
