A mystery element, called "muriaticum" by its discoverer, exists on Earth as a mixture of two isotopes. The most abundant isotope (75.76%) has a mass of 34.9689 amu; the other isotope (24.24%) has a mass of 36.9659. Calculate the average atomic mass (express your answer with the appropriate number of significant figures) and identify the element by its modern name.
