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 data:

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.

sure what is it? ^w^

thats how its supposed to be
