Question

there are two isotopes of the element X. 75% of existing element X is in the form X-33, which has a mass of 33.0132 amu. 25% of existing element X is in the form X-34, which has the mass of 34.0260 amu. what is the average atomic mass of element X? what could be the identity of elemnet X?

Answer 1

The average atomic mass of element X is 33.8651 amu. The identity of element X cannot be determined with the given information.

Step-by-step explanation:

To calculate the average atomic mass of element X, we can use the formula: average atomic mass = (mass of isotope 1 * relative abundance of isotope 1) + (mass of isotope 2 * relative abundance of isotope 2). Using the given information, we can calculate: (33.0132 amu * 0.75) + (34.0260 amu * 0.25) = 33.8651 amu. Therefore, the average atomic mass of element X is 33.8651 amu.

As for the identity of element X, we do not have enough information to determine it. The name and symbol of an element are not solely determined by its isotopes. We would need additional information, such as the number of protons or the chemical properties of element X, to identify it.
