4Na+O2 =2Na20


5,52g of Na reacts Completely with oxygen according to the given equation calculate the mass of oxygen that reacts and the yield mass of Na2O that is produced.How many moles of Na2O are produced?

Respuesta :

11.625 moles of Na₂O  are produced.

What do you mean by the term mole ?

A mole is defined as the amount of a substance that contains exactly 6.02214076 × 10²³ ‘elementary entities’ of the given substance.

It can be represented by the following formula:

n = N/NA

To calculate moles of Na₂ O   produced are -:

40 gm of sodium

3.00 gm of oxygen

4 Na+ Oâ‚‚----->2Naâ‚‚O

First calculate limiting reagent,

Stochiometric ratio,

a/b=4/1

=4

Molar ratio,

M/n=4/22/3/22=4/22×32/3

=1.93

As a/b>m/n

So, sodium is limiting reagent

4 Na+ Oâ‚‚----->2Naâ‚‚O

As 32 g of Oâ‚‚ produced =124 g of Naâ‚‚O

SO,

3 gm of O₂ produced =124×3/32

=11.625 gm

11.625 gm of Naâ‚‚O can be produced .
