​​A sample of oxygen gas occupies 431 ml at stp. calculate the volume if temperature is 35 degree celcius and pressure is 1.05 bar

Dear student
Please find the solution to the asked query:

$$\begin{gathered} Given at STP \\ Volume occupied V_1=431mL \\ Temperature at\hspace{0.17em}STP, T_1 = 273K \\ Pressure at STP, P_1 =1.013bar \\ Again, Temperature , T_2 = 273+35=308K \\ Pressure P_2= 1.05 bar \\ Volume V_2=? \\ We know, \\ \frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2} \\ Substituting the values we get: \\ \frac{1.013\times 431}{273}=\frac{1.05\times V_2}{308} \\ {V}_2 =469mL \end{gathered}$$
