Question

How many moles of SnF₂ will be produced along with 48 grams of H₂? *

Sn + 2HF (arrow) SnF2 + H2

12 moles
24 moles
48 moles
96 moles

Answer 1

Answer: 24 moles of
`SnF_2` are produced.

Step-by-step explanation:

To calculate the moles :

`\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}`

`{\text{Moles of} H_2}=(48g)/(2g/mol)=24moles`

`Sn+2HF\rightarrow SnF_2+H_2`

According to stoichiometry :

1 mole of
`H_2` is accompanied with = 1 mole of
`SnF_2`

Thus 24 moles of
`H_2` is accompanied with =
`(1)/(1)* 24=24moles` of
`SnF_2`

Thus 24 moles of
`SnF_2` are produced.
