Question

part a four dinitrogen monoxide molecules express your answer as an integer. submit previous answers request answer incorrect; try again; 2 attempts remaining

Explanation:

Step1: Identify the formula

To find the number of atoms in a given number of molecules, we use the formula: Number of atoms = Number of molecules × Number of atoms per molecule.
For dinitrogen monoxide ($N_2O$), each molecule contains 2 nitrogen atoms and 1 oxygen atom, so total atoms per molecule = 2 + 1 = 3.

Step2: Calculate the number of atoms

Given the number of dinitrogen monoxide molecules is 4.
So, number of atoms = 4 × 3 = 12.

Answer:

12
