Mass of Oxygen : 47.9

<h3>Further explanation</h3>

Given

2S03 (g)⇒ 2S02 (g) + O2 (g)

240 g SO3

Required

mass of Oxygen

Solution

mol SO3 :

= 240 g : 80.1 g/mol

= 2.996

From the equation, mol O2 :

= 1/2 x mol SO3

= 1/2 x 2.996

= 1.498

mass O2 :

= 1.498 mol x 32 g/mol

= 47.9

Mars2501 [29]

Answer:

1 mole FeCr2/ 1 mole FeCr2O4

Explanation:

We have to write down the equation of the reaction before we can answer the question;

2C(s) + FeCr2O4(s) -------> FeCr2(s) + 2CO2(g)

By inspection of this reaction equation, we can clearly see that the mole ratio of the reactants and products is 2:1:1:2.

Specifically, the ratio of chromites to ferrochrome is 1:1

Hence;

The mole ration required to convert chromites to ferrochrome is;

1 mole FeCr2/ 1 mole FeCr2O4
