How many grams of naf form when 0.589 mol of hf react with excess na2sio3?

6.18 g

Explanation:

We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

:                                             41.99  

                 Na₂SiO₃ + 8HF ⟶ 2NaF + H₂SiF₆ + 3H₂O  

n/mol:                         0.58    

1. Use the molar ratio of NaF:HF to calculate the moles of NaF.

2. Use the molar mass of NaF to calculate the mass of NaF.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
