Two atoms that are isotopes of one another must have different number of what?

1 answer:

8 0

For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

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.

ozzi

I think the correct answer would be false. The atomic mass of chlorine does not represent the mass of the most common naturally occurring isotope of chlorine. The atomic mass of any compound is the average of the atomic masses of the naturally occurring isotopes of an element.
