The question asks me to find the absolute error using the true value=.1025M, and the mean=.1077

The answer I got was .0052...how would I convert this to 4 significant figures? (since the values have 4 significant figures)

You can't get four s.f. but that isn't necessary. When one subtracts (or adds), the number may be as accurate as the least number of places; i.e., you have four places to the right of the decimal in 0.1025 and four to the right of the decimal in 0.1077. Therefore the answer may be four places to the right of the decimal or 0.0052 for the answer.
