grams.
2. How many MOLES of chlorine are present in 3.61 grams of sulfur dichloride ?
moles.
What is the percent S in SCl2?
%S = (atomic mass S/molar mass SCl2)*100 = ?
1.53 x (%S/100) = ?
b. moles SCl2 = grams/molar mass
Then you have 1 mole Cl2 in 1 mole SCl2.
a.0.4764
b.1mole
To answer these questions, we need to use the molar mass of sulfur dichloride, which is the sum of the atomic masses of sulfur and two chlorine atoms.
1. Calculating the grams of sulfur:
The molar mass of Sulfur Dichloride (SCl2) is:
(1 atom of Sulfur x atomic mass of Sulfur) + (2 atoms of Chlorine x atomic mass of Chlorine)
Atomic mass of Sulfur (S) = 32.07 g/mol
Atomic mass of Chlorine (Cl) = 35.45 g/mol
Molar mass of SCl2 = (1 x 32.07) + (2 x 35.45) = 102.97 g/mol
To calculate the grams of sulfur in 1.53 moles of sulfur dichloride, we use the molar mass conversion factor:
Grams = Moles x Molar Mass
Grams = 1.53 moles x 102.97 g/mol
Grams = 157.92 grams
Therefore, there are approximately 157.92 grams of sulfur in 1.53 moles of sulfur dichloride.
2. Calculating the moles of chlorine:
Using the molar mass calculated above, we can calculate the moles of sulfur dichloride from the given mass:
Moles = Grams / Molar Mass
Moles = 3.61 grams / 102.97 g/mol
Moles ≈ 0.035 moles
Therefore, there are approximately 0.035 moles of chlorine in 3.61 grams of sulfur dichloride.
To find the number of grams of sulfur in 1.53 moles of sulfur dichloride, you need to use the molar mass of sulfur dichloride. The molar mass of sulfur dichloride (SCl2) can be calculated by adding up the atomic masses of sulfur (S) and chlorine (Cl).
1. Calculate the molar mass of sulfur dichloride (SCl2):
Molar mass(S) = 32.07 g/mol (atomic mass of sulfur)
Molar mass(Cl) = 35.45 g/mol (atomic mass of chlorine)
Molar mass(SCl2) = molar mass(S) + 2 * molar mass(Cl) = 32.07 + 2 * 35.45 = 103.97 g/mol
2. Now, use the molar mass to convert moles of sulfur dichloride to grams:
Grams of SCl2 = moles of SCl2 * molar mass of SCl2
Grams of SCl2 = 1.53 mol * 103.97 g/mol
Grams of SCl2 = 159.07 g
Therefore, 1.53 moles of sulfur dichloride contains 159.07 grams of sulfur.
To find the number of moles of chlorine in 3.61 grams of sulfur dichloride, you need to use the molar mass of sulfur dichloride and the stoichiometry of the compound.
1. Calculate the molar mass of sulfur dichloride as explained above, which is 103.97 g/mol.
2. Use the molar mass to convert grams of sulfur dichloride to moles:
Moles of SCl2 = Grams of SCl2 / molar mass of SCl2
Moles of SCl2 = 3.61 g / 103.97 g/mol
Moles of SCl2 ≈ 0.0347 mol
Since the formula of sulfur dichloride (SCl2) contains two moles of chlorine for every one mole of sulfur dichloride, there are also 0.0347 moles of chlorine in 3.61 grams of sulfur dichloride.
Therefore, 3.61 grams of sulfur dichloride contains approximately 0.0347 moles of chlorine.
