How do you find the mass of the oxygen gas in the metal container
Weight the container full or empty !
the mass of the isotopes
density = mass / volume. so you need to weigh to find the mass. To find the volume submerse in water and record the displacement of water to find the volume.
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance

What do you use to find mass
You can find a dog's mass by wieghing it. Dogs usually have a different mass.
Use a mass balance to find the mass then find the volume by V=mass/density.
A mass-mass problem is a kind of problem wherein a person is asked to find an answer which is also a mass. In this, a person is given mass of a compound and then asked to find the mass of another compound.
Find the volume then divide the mass by the volume.
You have to find out its mass, and its volume. Then you divide its mass by its volume.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Atomic mass = Mass of protons + Mass of neutrons
mass fraction of Substance A = (mass of Sub. A) / (total mass)
Large mass
