The RFM of steel varies dependent upon the levels of differing impurities which give each specific type of steel its desired properties. You need to be more specific in you question. Which type of steel?
between which two of these times was the mass of the contents of the beaker
How do you find the mass of the oxygen gas in the metal container
When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.
Steel is an alloy (mixture of different metals/elements) and as such does not have an atomic mass. Its mass/volume ratio depends on how much iron to carbon is in it.
The mass is about 5 grams when it's empty.
So that you can calculate the mass of the contents alone, by subtracting the mass of the empty vial from the mass of the vial and contents.
Anything that is physically there (rocks, empty boxes, dog, water, air, inflated balloons etc) has mass.
No
The mass of the bottle will remain the same whether it's full or empty however, the weight will change.
The atomic mass of steel cannot be determined as it is an alloy made up of multiple elements, primarily iron and carbon, along with trace amounts of other elements. The atomic mass of steel will depend on the specific composition of the alloy.
