Question

Find the molecule of Oxyzen ​

Answer 1

The molecular formula of acetaminophen is: $\sf\text{ {C_{8}H_{9}NO_{2}} }$ Considering the atomic masses of the elements Carbon, Hydrogen, Nitrogen and Oxygen of respectively 12, 1, 14 and 16, let us determine the mass of the minimum formula.

❑ Determining the Minimum Formula of each element: $\pink{\sf \boxed{\begin{array}{lr} C = \dfrac{63.58}{12} = 5,298 \\\\ H = \dfrac{5.96}{1} = 5.96 \\\\ N = \dfrac{9.27}{14} = 0.662 \\\\ O = \dfrac{21.19}{16}= 1,324\end{array}}}$

❑ Now, let's take all the values and divide them by the smallest among them, in this case, 0.662: $\sf \boxed{\begin{array}{lr} C = 5,298/0.662\approx 8 \\ H = 5.96/0.662\approx 9 \\ N = 0.662/0.662 = 1 \\ O = 1.324/0.662 \approx 2\end{array}}$ Therefore, the molecular formula of Paracetamol is: $\large \text{ {C_{8}H_{9}NO_{2}} }$

Answer 2

Explanation:

Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule. O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu
