Considering the definition of molar mass, 1.096 moles of Allyl sulfide are in 125 g.
The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.
In this case, you know the molar mass of the elements is:
So, the molar mass of the compound C₆H₁₀S is calculated as:
C₆H₁₀S= 6× 12 g/mole + 10× 1 g/mole + 32 g/mole
Solving:
C₆H₁₀S= 114 g/mole
Next, you can apply the following rule of three: If by definition of molar mass 114 grams of the compound are contained in 1 mole, 125 grams of the compound are contained in how many moles?
[tex]amount of moles=\frac{125 grams x 1 mole}{114 grams}[/tex]
amount of moles= 1.096 moles
Finally, 1.096 moles of Allyl sulfide are in 125 g.
