The formula of zinc fluoride is ZnF2. Therefore, its molar mass is the sum of the Atomic Mass of zinc and twice the atomic mass of fluorine: 65.39 + 2(18.999) = 103.39; the last digit is depressed because it may not be significant, since the atomic mass of zinc (at least in my reference) has only four significant digits.

What is the mass of 8.1g of zinc oxide?
To find the mass of zinc in 8.1g of zinc oxide, you need to consider the atomic masses of zinc (Zn) and oxygen (O). The molar mass of ZnO is 81.38 g/mol. Since zinc accounts for 65.38% of the molar mass, the mass of zinc in 8.1g of ZnO is 8.1g * (0.6538) ≈ 5.3g.

If you have 125 grams of zinc how many moles of zinc do you have?
To calculate the number of moles of zinc, use the formula: moles = mass (grams) / molar mass (grams/mol). The molar mass of zinc (Zn) is approximately 65.38 g/mol. Therefore, 125 grams of zinc is equal to 125 g / 65.38 g/mol, which is about 1.91 moles of zinc.
If you have 125g of zinc how many moles of zinc do you have?
To find the number of moles of zinc, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of zinc is approximately 65.38 g/mol. Thus, for 125 g of zinc, the calculation would be 125 g / 65.38 g/mol, which equals approximately 1.91 moles of zinc.
