How many grams of Chlorine are present in 1 mole of CsCl? |
| There are 1 Cl-atoms in a CsCl molecule. • Atomic weight of a Cl-atom = 35.453 g/mol ∴ Total mass of Chlorine in 1 mole of CsCl = 1 x 35.453 = 35.45 g. Therefore there are 35.45 grams of Chlorine in 1 mole of CsCl. |
What is the mass of 2 mol of CsCl? |
| The molecular mass of CsCl is 168.3584 g/mol. This means 168.3584 grams of CsCl are present per mole. Therefore, we can find the mass of CsCl in 2 moles as follows: ∴ Moles = Mass/Molar Mass ∴ Mass of CsCl = Moles x Molar mass ∴ Mass of CsCl = 2 x 168.3584 = 336.72 g Thus, the mass of 2 mol of CsCl is 336.72 g. |
If you have 69.1247 grams of CsCl, how many moles do you have? |
| ∴ Moles = Mass/Molar mass ∴ Moles of CsCl = 69.1247/168.3584 = 0.4106 Thus, there are 0.4106 moles of CsCl in its 69.1247 grams. |
What is the mass in kg of 28.06 x 1025 molecules of CsCl? |
| 1 mole of a substance contains Avogadro number of particles i.e., 6.02 x 1023. Therefore, the number of moles in 28.06 x 1025 molecules of CsCl are: ∴ Moles of CsCl = 28.06 x 1025/6.02 x 1023 = 466.1
Now that we have its number of moles, so, we can use the molar mass of CsCl (168.3584 g/mol) to find its mass as shown below. ∴ Mass of CsCl = Moles x Molar mass
∴ Mass of CsCl = 466.1 x 168.3584 = 78473.29 g
Converting mass from grams (g) to kilograms (kg) gives us: ∴ Mass of CsCl = 78473.29/1000 = 78.47 kg
The mass of 28.06 x 1025 molecules of CsCl is 78.47 kg.

What is the molar mass and molecular weight of Cesium Chloride (CsCl)? |
CsCl is composed of 1 Chlorine (Cl), and 1 Cesium (Cs) atom.
To find the molecular mass of CsCl, one multiplies the atomic weight of each element by its number of atoms in the molecule and then sums the results. ∴ For CsCl, it’s (1 x 35.4530) + (1 x 132.9054).
Therefore, the molar mass of Cesium Chloride (CsCl) is 168.3584 g/mol.
