Question

What is the amount in moles of a 61 g sample of zinc fluoride, ZnF2 ? Show all your work.

Answer 1

84gm of znf2=1mole

62gam of Znf2=1/84*62=.72moles

Answer 2

Answer:

The number of moles of a 61 g sample of zinc fluoride is equal to 0.589 moles.

Explanation:

Given, the mass of the zinc fluoride = 61 g

The molecular mass of the zinc fluoride = 103.4g/mol

We know that we can find the number of moles by dividing the mass of the compound with its molar mass.

Number of moles = Mass/ Molecular mass

Number of moles of ZnF₂ =$=\frac{61}{103.4} = 0.589$ moles

Therefore, the number of moles of zinc fluoride in given mass is equal to 0.589 moles.

Zinc fluoride is an inorganic compound. Its is used in the manufacturing of phosphors for fluorescent lights, fluorination of organic compounds, in preserving wood, galvanizing steel, electroplating baths,  etc.
