Why does CH2Cl2 solvent (lower layer) have higher density than water while non-chlorinated solvents like hexanes and ether (top layer) have lower density than water, i.e. what exactly is it about Cl that causes this difference?

Think about the differences between chlorine and hydrogen and the components of density

Yes Cl MM is 35 while H is 1....Density =M/V...a little bit more explanation  would be helpful
