Is it possible that it is W = m * a

I'm not really sure what g is.
g is the acceleration due to gravity, a well-known constant (that I'm sure you're expected to know) that describes the strength of Earth's gravity near its surface. Read the link--it's there.

What book are you using?

Oh, I see. It is 9.8 m/s^2!
