Question

Complete the fourth column of the table.Express your answer using two significant figure

Answer 1

Using Avogadro's Law, we have

`(V_1)/(n_1)=(V_2)/(n_2)`

In the fourth column, we have to find n2.

`n_2=(V_2\cdot n_1)/(V_1)`

Where V1 = 8.66 L, V2 = 10.9 L, and n1 = 0.0021 mol.

`n_2=\frac{10.9L\cdot0.0021\text{mol}}{8.66L}=0.0026mol`

Therefore, n2 = 0.0026 moles.
