Given: 4na + o2 → 2na2o in this chemical reaction, how many moles of na2o will be produced if 2.90 moles of na react completely? express your answer to three significant figures. there will be moles of na2o.

1.45 moles of

Explanation:

According to the stoichiometry:

Given : Na react completely, thus sodium is a limiting reagent as it limits the formation of product. Oxygen will be excess reagent as it does not react completely.

4 moles of sodium produce 2 moles of

Thus 2.90 moles of sodium produce = moles of

Thus 1.45 moles of will be produced.

i think its 5049.

i hope this !

the answer is 0.42 is that is an option. this question provides no info
