Answer:
[tex]n=1.7 mol[/tex]
Explanation:
Hello!
In this case, according to the ideal gas equation, it is possible to notice that:
[tex]PV=nRT[/tex]
Thus, since we are asked to compute moles, we proceed as follows:
[tex]n=\frac{PV}{RT}[/tex]
Now, since 1 L = 1 dm³ and 20 °C equal 293.15 K, we obtain:
[tex]n=\frac{4atm*10 L}{0.08206\frac{atm*L}{mol*K}*293.15K}\\\\n=1.7 mol[/tex]
Best regards!
