Here Is a Bivariate Table with Observed Counts and Expected

Here is a bivariate table with observed counts and expected counts. What is the value of chi-square for this table?

$$\begin{array} { | l l | c | c | } \hline& & { \text { RACE } } \\\hline \text { SEX } && \text { white } & \text { black } \\\hline \text { male } & \text { observed } &2&6&8\\& \text { expected } & 4 & 4 \\\hline\end{array}$$
$$\begin{array} { | l r | l | l | l } \hline \text { female }&\text { observed } & 6 & 2&8 \\&\text { expected } & 4 & 4 & \\\hline&&8&8&16\\\end{array}$$
chi-square = __________
