Find the mass of 3.66 moles of Octane C, H,8

417.2g

Explanation:

Given parameters:

Number of moles of octane  = 3.66moles

Unknown:

Mass of octane  = ?

Solution:

To solve this problem;

         Octane = C₈ H₁₈

  Mass of octane  = number of moles x molar mass

     Molar mass of octane = 8(12) + 18(1)  = 114g/mol

 Mass of octane  = 3.66 x 114  = 417.2g
