Answer:

#"Density, "rho# #~=# #1.3*g*cm^-3#.

Explanation:

#"Density, "rho# #-=# #"Unit mass"/"Unit Volume"#

Here, both mass and volume were quoted, and we simply take the quotient, knowing that #1*L# #=# #1000*cm^3#.

Thus #"rho# #-=# #(3.15xx10^3g)/(2.50*cancelLxx10^3*cm^3*cancel(L^-1))# #=# #??g*cm^-3#
