Question

count the atoms! 6hnco

Explanation:

Step1: Identify number of each atom in one unit

In one unit of HNCO, there is 1 H, 1 N, 1 C, and 1 O atom.

Step2: Multiply by the coefficient

The coefficient is 6. So for H: $6\times1 = 6$, for N: $6\times1=6$, for C: $6\times1 = 6$, for O: $6\times1=6$.

Step3: Calculate total number of atoms

Total atoms = $6 + 6+6 + 6=24$.

Answer:

24
