How

12.6

Sn + 2 HF - Snf a + H₂

many moles of tin (11) Fluoride will be produced

grams of hydrogen fluoride react?

if

12.6 gram of HF will produced 0.315 moles of SnF₂

Explanation:

Given dа ta:

Mass of HF = 12.6 g

Moles of Tin fluoride produced = ?

Solution:

Chemical equation:

Sn + 2HF → SnF₂ + H₂

Number of moles of HF:

Number of moles = mass / molar mass

Number of moles = 12.6 g/20.01 g/mol

Number of moles = 0.63 mol

Now we will compare the moles of HF with SnF₂.

HF : SnF₂

2 : 1

0.63 : 1/2*0.63 = 0.315 mol

So 12.6 gram of HF will produced 0.315 moles of SnF₂.
