Answer:

Explanation:

Hi there!

2Pb (no₃) -------> 2Pb + 4no₂ + o₂

Molecular mass of 4no₂ = 184g

Molecular mass of o₂ = 32g

From the reaction;

When 184 g of no₂ was formed 32 g of oxygen was formed.

When 1 g of no₂ was formed 32/184 g of oxygen was formed.

When 11.5 g of no₂ was formed (32/184)*11.5 g of oxygen was formed.

Therefore, when 11.5 g of no₂ was formed 2 g of oxygen was formed.

Hope it helps!
