Question

A student performed the following reaction: 2 A + B2 --> 2AB

How many grams of AB are produced when 88 g of A reacts with 28 g B2?

Answer 1

116g

Step-by-step explanation:

Given parameters:

Mass of A = 88g

Mass of B₂ = 28g

Unknown:

Mass of AB produced = ?

Solution:

The reaction expression is given as:

2A + B₂ → 2AB

According to the law of conservation of matter "matter is neither created nor destroyed but changed from one form to another".

In retrospect;

Mass of A + Mass of B₂ = Mass of AB

Now insert the parameters and solve;

Mass of AB = 88g + 28g = 116g
