Question

If you start with 1.5 moles of H2O, how many moles of H4SiO4 do you make?

Answer 1

0.75moles of H₄SiO₄

Step-by-step explanation:

Given parameters:

Number of moles of H₂O = 1.5moles

Unknown:

Number of moles of H₄SiO₄ = ?

Solution:

To solve this problem, we need to write the reaction equation first;

SiO₂ + 2H₂O → H₄SiO₄

From the balanced reaction equation:

2 moles of water will produce 1 mole of H₄SiO₄

So 1.5 moles of water will produce
`(1.5)/(2)` = 0.75moles of H₄SiO₄
