Question

how u calculate atomic mass of oxygen​

Answer 1

Hey dude here is your Answer------------------------ ✔️✔️✔️✔️✔️✔️

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

Oxygen's atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? Molar mass (in grams) is always equal to the atomic weight of the atom!...

Answer 2

Answer:

$\huge\mathfrak\green{{Here~is~your~Answer}}$

1 mole of oxygen contains 16 g

Means

1 mole of oxygen = 16 g

$6.022 \times {10}^{23}$ atoms of oxygen = 16 g

1 atom of oxygen = $\frac{16}{(6.022 \: \times \: {10}^{23}) }$

→ $2.65 \: \times \: {10}^{ - 23} g$
