A man walks 30 m to the west, then 5 m to the east in 45 seconds.
What is his average speed?

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?
