Answer

Answer:

1.45

Explanation:

Step1: Identify mole - ratio

The balanced chemical equation is (4Na + O_2\rightarrow2Na_2O). The mole - ratio of (Na) to (Na_2O) is (4:2) or (2:1).

Step2: Calculate moles of (Na_2O)

Given (n_{Na}=2.90) moles. Using the mole - ratio (\frac{n_{Na_2O}}{n_{Na}}=\frac{1}{2}), so (n_{Na_2O}=\frac{n_{Na}}{2}). Substituting (n_{Na} = 2.90) moles, we get (n_{Na_2O}=\frac{2.90}{2}=1.45) moles.
