Answer:

#430.g#

Explanation:

This is simple unit conversion!

Start by converting the density to something favorable:

#(1.11g)/(cm^3)*(cm^3)/(mL) = (1.11g)/(mL)#

Now things don't seem confusing, do they?

#387mL * (1.11g)/(mL) approx 430.g#

The period indicates three significant figures, what is required in this problem.
