How many grams of Chlorine are present in 1 mole of C2Cl4? |
| There are 4 Cl-atoms in a C2Cl4 molecule. • Atomic weight of a Cl-atom = 35.453 g/mol ∴ Total mass of Chlorine in 1 mole of C2Cl4 = 4 x 35.453 = 141.81 g. Therefore there are 141.81 grams of Chlorine in 1 mole of C2Cl4. |
What is the mass of 6 mol of C2Cl4? |
| The molecular mass of C2Cl4 is 165.8340 g/mol. This means 165.8340 grams of C2Cl4 are present per mole. Therefore, we can find the mass of C2Cl4 in 6 moles as follows: ∴ Moles = Mass/Molar Mass ∴ Mass of C2Cl4 = Moles x Molar mass ∴ Mass of C2Cl4 = 6 x 165.8340 = 995.00 g Thus, the mass of 6 mol of C2Cl4 is 995.00 g. |
If you have 68.6198 grams of C2Cl4, how many moles do you have? |
| ∴ Moles = Mass/Molar mass ∴ Moles of C2Cl4 = 68.6198/165.8340 = 0.4138 Thus, there are 0.4138 moles of C2Cl4 in its 68.6198 grams. |
What is the mass in kg of 27.64 x 1025 molecules of C2Cl4? |
| 1 mole of a substance contains Avogadro number of particles i.e., 6.02 x 1023. Therefore, the number of moles in 27.64 x 1025 molecules of C2Cl4 are: ∴ Moles of C2Cl4 = 27.64 x 1025/6.02 x 1023 = 459.1
Now that we have its number of moles, so, we can use the molar mass of C2Cl4 (165.8340 g/mol) to find its mass as shown below. ∴ Mass of C2Cl4 = Moles x Molar mass
∴ Mass of C2Cl4 = 459.1 x 165.8340 = 76137.64 g
Converting mass from grams (g) to kilograms (kg) gives us: ∴ Mass of C2Cl4 = 76137.64/1000 = 76.14 kg
The mass of 27.64 x 1025 molecules of C2Cl4 is 76.14 kg.
