Molar mass of zinc?
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.
A certain metal hydroxide rm MOH2 contains 32.8 oxygen by mass What is the identity of the metal M?
many other sites say it is zinc, but it is actually copper as the molar mass of a certain metal hydroxide is 97.56. Using the molar mass formula the answer is 63.54 which has a molar mass closer to Copper than zinc.
How many moles are in 22.5 grams of zinc?
For this you need the atomic mass of Zn. Then take the mass in grams and divide it by the atomic number (multiplied by one mole for units to cancel) to find number of moles. Zinc's atomic mass is 65.4 grams.22.5 g Zn / (65.4 grams) = .344 moles Zn
How do you find the molar mass of ZnF2?
The atomic weight of zinc is: 65,38 The atomic weight of fluorine is: 18,998 403 2 The molecular mass of zinc difluoride is by consequence: 65,38 + 2 x 18,998 403 2. And M= 103,406 g/mol (for the anhydrous molecule)
What mass of carbon dioxide is formed when 125g of zinc carbonate decomposes?
125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer
The mass of a mole of zinc is approximately?
The molar mass of zinc is 65,38 g.

What is the mass of 0.06 moles of zinc?
.06x molar mass of zinc which is the atomic mass so 3.9228 g
What is the molar mass of Zn2SO4?
The molar mass of zinc sulfate - ZnSO4 - is 161,47 g.

What is the molar mass of yellow brass?
Yellow brass is an alloy, and thus can be present with a variety of percentages of copper and zinc. There is no definite molar mass.
What mass of carbon dioxide is formed when 125g of zinc carbonate decomposes?
125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer
What is 1.66 moles converted to grams?
This depends on what element/molecule you're converting. You use the molar mass. (The sum of atomic mass of all the elements you're using.) Divide .00336 (since that what I'm assuming you meant) by the molar mass. For an example of one element, it would look like this: .00336 grams of Carbon converted to moles. Carbon's molar mass is approximately 12. (.00336)/ (12) = 2.8 X10-4 (or .00028) moles. For an example of a molecule, it would look like this: .00336 grams of Ammonium Chloride converted to moles. Ammonium: NH4 Ammonium Chloride: NH4Cl N's molar mass: 14 H's molar mass: 1 (but there's 4 of them, so multiply by 4): 4. Cl's molar mass: 35.45 Add them all together: 53.45 (.00336g)/53.45 = 6.29 x 10-5 (.0000629) moles.
What is the mass of zinc iodide formed if 1 mole of zinc reacts with one mole of iodine molecules?
Balanced equation. Zn + I2 --> ZnI2 All is one to one, so it does not matter what is limiting and what drives this reaction. We will use zinc as the driver of convenience. 1 mole Zn (1 mole ZnI2/1 mole Zn)(319.21 grams/1 mole ZnI2) = 319.21 grams zinc iodide produced ==========================
What is the formula of zinc perchlorate?
The formula for zinc perchlorate is Zn(ClO4)2. Zn = zinc Cl = chlorine O = oxygen Its molar mass is 264.2812.
