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!
