If element x consists of 78.7% of atoms with a mass of 24.0 amu, 10.1% of atoms with a mass of 25.0 amu, and 11.2% of atoms with a mass of 26.0 amu. what is the average atomic mass of element x?

Average mass of element X can be calculated by taking sum of masses of atoms in the element multiplied by their percentage.

Here, masses of atoms and their percentage is given as follows:

24.0 amu mass has 78.7 % abundance, 25.0 amu has 10.1% abundance and 26.0 amu has 11.2% abundance thus, atomic mass is:

Therefore, atomic mass of element X will be 24.325 amu.

Newton’s third law of motion states that, for every action, there is an equal and opposite reaction. Based on this law, wings are forced upwards because they are tilted, pushing air downwards so the wings get pushed upwards. This is the angle of attack or the angle at which the wing meets the airflow.

So, this will be (Newton’s third Law)
Have a good day!
