To solve the given equation:

\[
C = \frac{5}{9}(68 - 32)
\]

1. First, calculate the expression inside the parentheses:

\[
68 - 32 = 36
\]

2. Substitute the result into the equation:

\[
C = \frac{5}{9} \times 36
\]

3. Now, perform the multiplication:

\[
C = \frac{5 \times 36}{9} = \frac{180}{9} = 20
\]

Thus, the value of \( C \) is 20.
