The relative atomic mass of the element is 15.99 and the element is oxygen.
<h3>What is the relative atomic mass of the element?</h3>Let us note that owing to the fact that elements often have isotopes, the relative atomic mass is not always a whole number. Now we have tp obtain the relative atomic mas from the atomic masses of the elements.
Thus;
X = (15.99 * 0.99762) + (16.999 * 0.00038) + (17.999 * 0.002)
X = 15.95 + 0.0065 + 0.036
X= 15.99
Thus the relative atomic mass of the element is 15.99 and the element is oxygen.
