Answer:
=242.47 g of HF
Step-by-step explanation:
From the equation One mole of SiO₂ (Silicon (IV) Oxide) react with 4 moles of HF (Hydrogen fluoride).
This is because the reaction ratio is 1:4
The number of moles in182 grams of SiO₂ is:
Number of moles= Mass/RMM
RMM of SiO₂ is 60.08 g/mol
No. of moles=182g/60.08g/mol
=3.0293 moles.
The reaction ratio of SiO₂ to HF is 1:4
Thus the number of moles of HF required to react with 3.0293 moles of SiO₂ is:
(4×3.0293)/1= 12.1172 moles
The mass of 12.1172 moles of HF is.
12.1172 moles× RMM of HF
=12.1172 moles×20.01 g/mol
=242.47 g of HF
