Question

What mass of sodium chromate in grams is needed to produce

5.17
mol
of sodium nitrate?

Answer 1

The question is incomplete, complete question is :

For the following chemical reaction, what mass of sodium chromate in grams will be needed to produce 5.17 mol of sodium nitrate?

`2AgNO_3 + Na_2CrO_4\rightarrow Ag_2CrO_4 + 2NaNO_3`

Answer:

418.77 grams of sodium chromate is needed to produce 5.17 mol es of sodium nitrate.

Step-by-step explanation:

`2AgNO_3 + Na_2CrO_4\rightarrow Ag_2CrO_4 + 2NaNO_3`

According to reaction, 2 moles of sodium nitarte is obtained from 1 mole of sodium chromate .

Then 5.17 moles of sodium nitarte will be obtained from :

`(1)/(2)* 5.17 mol=2.585 mol` of sodium chromate

Mass of sodium chromate :

`2.585* 162 g/mol=418.77 g`

418.77 grams of sodium chromate is needed to produce 5.17 mol es of sodium nitrate.
