120 grams of HF are needed to react with 3.0 moles of Sn

Explanation:

The balanced chemical equation is :

According to stoichiometry:

1 mole of reacts with 2 moles of HF

Thus 3.0 moles of Sn will react = moles of HF

Mass of

Thus 120 grams of HF are needed to react with 3.0 moles of Sn

lol for the pointsss
