What is the approximate mass of an oxygen atom in atomic mass units?
What is the approximate mass of two oxygen atoms?
How about an oxygen molecule?
To find the approximate mass of an oxygen atom in atomic mass units (amu), we can consult the periodic table.
1. Look up the atomic mass of oxygen on the periodic table - it is around 16.00 amu.
Therefore, the approximate mass of an oxygen atom is around 16.00 amu.
To calculate the approximate mass of two oxygen atoms:
2. Multiply the mass of one oxygen atom by 2.
16.00 amu * 2 = 32.00 amu
Therefore, the approximate mass of two oxygen atoms is 32.00 amu.
Now, let's move on to calculating the approximate mass of an oxygen molecule:
3. The molecular formula of oxygen is O2, meaning it consists of two oxygen atoms bonded together.
Since we already know the mass of two oxygen atoms (32.00 amu), we do not need to perform any additional calculations.
Therefore, the approximate mass of an oxygen molecule (O2) is also 32.00 amu.
