The molecular formula of sodium oxide is Na2O.

To find the number of moles of sodium oxide, use the formula:

n = m / M

Let’s calculate the molar mass of sodium oxide:

M (Na2O) = 2 * Na + 1 * O = 2 * 23 g / mol + 1 * 16 g / mol = 62 g / mol.

n (Na2O) = m (Na2O) / M (Na2O) = 50 g / 62 g / mol = 0.806 mol.

Answer: 0.806 mol.
