Question

If you start with 30 moles of O2, how many moles of SiO2 can you make?

Answer 1

30moles of SiO₂

Step-by-step explanation:

Given parameters:

Number of moles of O₂ = 30moles

Unknown:

Number of moles of SiO₂ = ?

Solution:

To solve this problem, we need to write the reaction expression:

Si + O₂ → SiO₂

The reaction is balanced;

1 mole of O₂ will produce 1 mole of SiO₂

30mole of O₂ will produce 30moles of SiO₂
