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:

$n = \dfrac{m}{MM}$

$5.20\:\:\diagup\!\!\!\!\!\!\!mol = \dfrac{m}{84\:g/\diagup\!\!\!\!\!\!\!mol}$

$m = 5.20*84$

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