guajiro [1.7K]

Answer:

C_2H_6N

Explanation:

Hello,

In this case, considering the given percentages, we compute the mole ratios as shown below:

n_C=\frac{0.545}{12}=0.0454\\n_H=\frac{0.1373}{1}=0.1373\\n_N=\frac{0.3177}{14}=0.0227

Now, by dividing all the mole ratios by the smallest ratio, we obtain the subscripts for the required empirical formula as shown below:

C=\frac{0.0454}{0.0227} =2\\H=\frac{0.1373}{0.0227}=6\\N=\frac{0.0227}{0.0227}=1

Therefore, the empirical formula turns out:

C_2H_6N

Best regards.

During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
