Question

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

Answer 1

Using Avogadro's Law, we have

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

In the fourth column, we have to find n2.

$n_2=\frac{V_2\cdot n_1}{V_1}$

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.
