How many grams of Oxygen are present in 1 mole of ZnCO3? |
| There are 3 O-atoms in a ZnCO3 molecule. • Atomic weight of a O-atom = 15.9994 g/mol ∴ Total mass of Oxygen in 1 mole of ZnCO3 = 3 x 15.9994 = 48.00 g. Therefore there are 48.00 grams of Oxygen in 1 mole of ZnCO3. |
What is the mass of 5 mol of ZnCO3? |
| The molecular mass of ZnCO3 is 125.3892 g/mol. This means 125.3892 grams of ZnCO3 are present per mole. Therefore, we can find the mass of ZnCO3 in 5 moles as follows: ∴ Moles = Mass/Molar Mass ∴ Mass of ZnCO3 = Moles x Molar mass ∴ Mass of ZnCO3 = 5 x 125.3892 = 626.95 g Thus, the mass of 5 mol of ZnCO3 is 626.95 g. |
If you have 41.0772 grams of ZnCO3, how many moles do you have? |
| ∴ Moles = Mass/Molar mass ∴ Moles of ZnCO3 = 41.0772/125.3892 = 0.3276 Thus, there are 0.3276 moles of ZnCO3 in its 41.0772 grams. |
What is the mass in kg of 20.90 x 1025 molecules of ZnCO3? |
| 1 mole of a substance contains Avogadro number of particles i.e., 6.02 x 1023. Therefore, the number of moles in 20.90 x 1025 molecules of ZnCO3 are: ∴ Moles of ZnCO3 = 20.90 x 1025/6.02 x 1023 = 347.1
Now that we have its number of moles, so, we can use the molar mass of ZnCO3 (125.3892 g/mol) to find its mass as shown below. ∴ Mass of ZnCO3 = Moles x Molar mass
∴ Mass of ZnCO3 = 347.1 x 125.3892 = 43528.38 g
Converting mass from grams (g) to kilograms (kg) gives us: ∴ Mass of ZnCO3 = 43528.38/1000 = 43.53 kg
The mass of 20.90 x 1025 molecules of ZnCO3 is 43.53 kg.

What is the molar mass and molecular weight of Zinc carbonate (ZnCO3)? |
ZnCO3 is composed of 3 Oxygen (O), 1 Carbon (C), and 1 Zinc (Zn) atom.
To find the molecular mass of ZnCO3, one multiplies the atomic weight of each element by its number of atoms in the molecule and then sums the results. ∴ For ZnCO3, it’s (3 x 15.9994) + (1 x 12.0110) + (1 x 65.3800).
Therefore, the molar mass of Zinc carbonate (ZnCO3) is 125.3892 g/mol.
