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

0.75moles of  H₄SiO₄

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   = 0.75moles of  H₄SiO₄

1. they vary with a higher number because boiling is way hotter than melting

i believe the answer is three water molecules
