The mass of mole of zinc equals the atomic mass of zinc expressed in?
grams. This means that one mole of zinc weighs the same as the atomic mass of zinc in grams, which is approximately 65.38 grams.
What is the atomic mass of zinc?
The atomic mass of zinc (Zn) is approximately 65.38 u (atomic mass units).
What mass in grams of hydrogen of 120 moles of zinc are added to hydrochloric acid?
To find the mass of hydrogen produced from 120 moles of zinc reacting with hydrochloric acid, we first note the balanced chemical reaction: [ \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 ] From the reaction, 1 mole of zinc produces 1 mole of hydrogen gas. Therefore, 120 moles of zinc will produce 120 moles of hydrogen. The molar mass of hydrogen (H₂) is approximately 2 grams per mole, so the mass of hydrogen produced is: [ 120 , \text{moles} \times 2 , \text{g/mole} = 240 , \text{grams} ]
How much zinc by weight in zinc chloride?
Zinc chloride (ZnCl₂) consists of zinc and chlorine in a 1:2 ratio. The molar mass of zinc is approximately 65.38 g/mol, and that of chlorine is about 35.45 g/mol. In one mole of zinc chloride, the total molar mass is around 136.29 g/mol, which means that zinc makes up about 48% of the weight of zinc chloride. Therefore, in any given weight of zinc chloride, roughly 48% of that weight would be zinc.
Which gas has the lowest mass per mole?
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
The molar mass of a mole of zinc is approximately?
65.4
The mass of mole of zinc equals the atomic mass of zinc expressed in?

What is zinc's mass?
Zink is a non metal element. Atomic Mass of it is 65.39.
How many moles of atom is contained in 15 gram of zinc?
To find the number of moles of zinc in 15 grams, divide the given mass by the molar mass of zinc. The molar mass of zinc is approximately 65.38 g/mol. Therefore, 15 grams of zinc is equal to 0.23 moles of zinc.
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.
What mass of zinc metal is required to produce 2.40g of zinc chloride?
To calculate the mass of zinc metal required to produce zinc chloride, you need to find the molar mass of zinc chloride (ZnCl2). The molar mass of ZnCl2 is 136.3 g/mol, which means that for every mole of ZnCl2 produced, you need 1 mole of zinc metal. Since 1 mole of ZnCl2 corresponds to 2 moles of zinc (from the formula ZnCl2), the mass of zinc metal required is 2.40g * (65.38 g Zn/ 136.3 g ZnCl2) = 1.15g.
The molar mass of a mole of sodium is approximately?
The molar mass of sodium is approximately 23 grams per mole.
What is the atomic mass of zinc?
The atomic mass of zinc (Zn) is approximately 65.38 u (atomic mass units).
How many atoms are in 100g of zinc?
To calculate the number of atoms in 100g of zinc, you first need to determine the molar mass of zinc, which is approximately 65.38 g/mol. Next, divide the given mass by the molar mass to find the number of moles of zinc. Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
What mass of carbon dioxide is formed when 125g of zinc carbonate decomposes?
The chemical equation for the decomposition of zinc carbonate is ZnCO3 → ZnO + CO2. From the equation, we see that 1 mole of zinc carbonate produces 1 mole of carbon dioxide. Zinc carbonate has a molar mass of 125.4 g/mol and carbon dioxide has a molar mass of 44.01 g/mol. By using stoichiometry, we can calculate that 125g of zinc carbonate produces 44.01g of carbon dioxide.
What is the mass of 1 mole of argon?
The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
In grams how much does zinc weigh?
Depends on how much zinc you have. 6.02 x 1023 atoms of zinc weighs about 65.409g 1 cubic centimeter of zinc weighs about 7.1 grams (1/4 ounce).
