Question

If 10. g of tin(IV) oxide are reacted with excess carbon, how many grams of tin metal can be produced?

SnO2 + C --> CO2 + Sn
4.2 g.
150.7 g
3.9 g.
7.8 g.

Answer 1

Given:

Mass of reacted with carbon = 10 gm

Chemical Reaction ⇒ SnO2 + C --> CO2 + Sn

To Find:

Mass of tin produced by the reaction.

Calculation:

- Molecular mass of tin = 119 gm

- Molecular mass of tin(IV) oxide = 151 gm

- According to the given reaction:

Mass of tin produced by 151 gm of tin(IV) oxide = 119 gm

⇒ Mass of tin produced by 10 gm of tin(IV) oxide = (119/151) × 10

⇒ Mass of tin produced by 10 gm of tin(IV) oxide = 7.88 gm

- So, 10 gm of tin(IV) oxide on reaction with excess carbon produces 7.88 gm tin.

- The correct answer is option (d) 7.88 gm
