Grams are mass. There's no calculation involved.
To determine the density of 10 grams of granular zinc, you would divide the mass (10g) by the volume. First, measure the volume of the zinc using a graduated cylinder. Then, divide the mass by the volume to calculate the density (Density = Mass/Volume).
To calculate the mass of hydrogen produced when 31.8g of zinc reacts with sulfuric acid, you need to first balance the chemical equation. The balanced equation is: Zn + H2SO4 → ZnSO4 + H2. Then, use the molar ratio from the balanced equation to convert the mass of zinc to moles, and then to moles of hydrogen. Finally, convert moles of hydrogen to mass using the molar mass of hydrogen.
*first you set the equation: -(10mL of HCl)(1 mol of HCl)/(22.4 mL of HCl)= .446 mol of HCl *you divide by the volume of HCl which is 22.4 at STP. *Then you will divide that .446 mol of HCl with the mol of Zn, which is 1: -(.446 mol of HCl)( I mol of Zn)/(1 mol of HCl)= .446 mol Zn
No, 500 g of zinc metal weighs more than 200 g of zinc metal. Weight is directly proportional to the mass of an object; therefore, a higher mass will result in a higher weight.
The atomic number of zinc (Zn) is 30. The atomic weight of Zn is 65.39 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
I would guess 250 grams.
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.
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.
To calculate the grams of zinc containing 6x10^23 atoms, we need to determine the molar mass of zinc, which is approximately 65.38 g/mol. Then, we can use Avogadro's number to find the number of moles (n) of zinc atoms: n = (6x10^23 atoms) / (6.022x10^23 atoms/mol). Finally, we can calculate the mass of zinc: mass = n x molar mass.
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.
For every 1 gram of zinc, 3.88 grams of iodine are required to react. So in this case, with 4.2 grams of zinc, the amount of iodine needed would be (4.2 grams zinc) * (3.88 grams iodine / 1 gram zinc) = 16.296 grams of iodine.
To determine the density of 10 grams of granular zinc, you would divide the mass (10g) by the volume. First, measure the volume of the zinc using a graduated cylinder. Then, divide the mass by the volume to calculate the density (Density = Mass/Volume).
Around room temperature, zinc has a density of 7.14 grams cm-3. So, Volume = Mass/Density = 213/7.14 cm3 = 29.8 cm3 (Exactly 30 cm3 if you calculate using density = 7.1 g cm-3).
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
The molar mass of zinc is approximately 65.38 grams per mole, as zinc has an atomic mass of 65.38 amu.
