Question

Determine the mass of 5.20 moles of C6H12

Answer 1

Hello!
We have the following data:

m (mass) = ?
n (number of moles) = 5.20 moles
MM (Molar mass of C6H12)
C = 6*12 = 72 amu
H = 12*1 = 12 amu
--------------------------
MM (Molar mass of C6H12) = 72 + 12 = 84 g/mol

Now, let's find the mass, knowing that:


`n = (m)/(MM)`


`5.20\:\:\diagup\!\!\!\!\!\!\!mol = (m)/(84\:g/\diagup\!\!\!\!\!\!\!mol)`


`m = 5.20*84`


`\boxed{\boxed{m = 436.8\:g}}\end{array}}\qquad\checkmark`
