Calculate the molar mass of each of the following to two decimal places. a.) Dinitrogen tetroxide Circle or highlight your answer.

92.01 g/mol

Explanation:

Step 1: Required data

Molar mass of nitrogen (M(N)): 14.0067 g/mol

Molar mass of oxygen (M(O)): 15.999 g/mol

Step 2: Calculate the molar mass of dinitrogen tetroxide

Dinitrogen tetroxide has the chemical formula N₂O₄. We can calculate the molar mass of this compound by adding the molar masses of the elements that form it.

M(N₂O₄) = 2 × M(N) + 4 × M(O)

M(N₂O₄) = 2 × 14.0067 g/mol + 4 × 15.999 g/mol

M(N₂O₄) = 92.009 g/mol ≈ 92.01 g/mol

30

Explanation:

(i dont know if its correct i am in a rush,)

Number of neutrons = 56 – 26 = 30. Thus there are 30 neutrons in a single $F{{e}^{2+}}$ atom. Note: Neutron is generally a subatomic particle which is neutral in charge. Mass of the neutron is slightly greater than the mass of the proton.
