8 0

Answer:

21.344%

Explanation:

For the given chemical reaction, 8 moles of the reactant should produce 4 moles of Na_{2}O. However, 195 g of Na_{2}O was produced instead. The molar mass of Na_{2}O is 61.9789 g/mol.

Thus, the moles of Na_{2}O produced = 195/61.9789 = 3.1462 moles

The percent error = [(Actual -Experiment)/Actual]*100%

The percent error =  [(4.00 - 3.1462)/4.00]*100% = (0.85376/4.00)*100% = 21.344%
