The density of helium is .164 kg *m^-3. What is this density in lb * ft^-3?

1 kg=2.20 lb and 1 m= 3.28 ft.

Please explain your answer. Thank you!

The missing component to the table to the right or indicated with orange letters complete the table by filling in the corresponding numbers or symbols

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.

In general metals get as you move from left to right across the periodic table.
