Answer:

#"Mass"# #=# #3.42*kg#

Explanation:

#rho,"density"="Mass"/"Volume"#.

Thus #"mass"=rhoxx"volume"=1.14*kg*cancel(L^-1)xx3.0*cancelL#

#=3.42*kg#.

As I recall, liquid nitrogen is a lot less dense. It is interesting to reflect that water ice would float in liquid oxygen. (The next time I get some liquid oxygen, I am going to try this!)
