Question

Given:

BO3 + 3Mg → 3MgO + B
1. How many moles of Mg are required if 2 moles of B are produced?

Answer 1

6moles of Mg

Step-by-step explanation:

The reaction expression is given as:

BO₃ + 3Mg → 3MgO + B

Given:

Number of moles of B produced = 2 moles

Unknown:

Number of moles of Mg required = ?

Solution:

From the balanced reaction expression:

1 mole of B is produced from 3 moles of Mg

2 moles of B will be produced from 2 x 3 = 6moles of Mg
