calculate the mass of the following 1)3.11* 10 to the power 23 atoms of o.
I do not recognize what you are calling the subject. What language is kendriya vidyalaya?
That number of atoms is 2.0 moles. If they are O atoms, there are 16 grams per mole. That makes a total of 32 grams.

OK, I have looked up the meaning of 'kendriya vidyalaya'.
It is the name of your central school system in India. It is not the school subject of your question.
To calculate the mass of a given number of atoms, you need to know the atomic mass of the element in question. The atomic mass of oxygen (O) is approximately 16 grams.
Now, follow these steps to calculate the mass of 3.11 * 10^23 atoms of oxygen:
Step 1: Determine the number of moles of oxygen atoms.
Divide the given number of atoms (3.11 * 10^23) by Avogadro's number, which is approximately 6.022 * 10^23. This will give you the number of moles of oxygen atoms.
Number of moles = (3.11 * 10^23 atoms) / (6.022 * 10^23 atoms/mol)
Step 2: Calculate the mass of oxygen atoms.
Multiply the number of moles of oxygen atoms by the atomic mass of oxygen (16 grams/mol). This will give you the mass of oxygen atoms.
Mass = Number of moles * Atomic mass
Mass = (Number of moles) * (Atomic mass)
Mass = ((3.11 * 10^23 atoms) / (6.022 * 10^23 atoms/mol)) * (16 grams/mol)
After performing the calculations, you will obtain the mass of 3.11 * 10^23 atoms of oxygen.
