Answer:
The new volume is 2249.28 mL.
Step-by-step explanation:
According to Avogadro's Law, the number of moles in a gas is directly proportional to the volume.
Initial no of moles are 0.504 moles at a volume of 2680 mL.
It is required to find the volume if number of moles changes to 0.423 moles.
Using Avogadro's Law,
![(n_1)/(n_2)=(V_1)/(V_2)\\\\(0.504)/(0.423)=(2680)/(V_2)](https://img.qammunity.org/2021/formulas/chemistry/middle-school/8sbu2zr4pi0jlt94omir8apcpf3zl8n7k0.png)
![(0.504)/(0.423)=(2680)/(V_2)\\\\V_2=(0.423 * 2680)/(0.504)\\\\V_2=2249.28\ mL](https://img.qammunity.org/2021/formulas/chemistry/middle-school/c8r1t1x7tekcjf93bv02e6kzug9govjuz0.png)
So, the new volume is 2249.28 mL.
