MCQ
Mass of one atom of oxygen is formul:
  • A
    $\frac{16}{6.023\times10^{23}}\text{g}$
  • B
    $\frac{32}{6.023\times10^{23}}\text{g}$
  • C
    $\frac{1}{6.023\times10^{23}}\text{g}$
  • D
    $8\text{u}$

Answer

  1. $\frac{16}{6.023\times10^{23}}\text{g}$

Explanation:

Oxygen's atomic weight is 16.00amu. 1mole of oxygen is 6.02 × 1023 atoms of oxygen 1amu = 1.661 × 10 -24g

Molar mass (in grams) is always equal to the atomic weight of the atom.
