suppose hypothetical element consists mixture two isotopes one isotope having mass 44 amu

Suppose that a hypothetical element consists of a mixture of two isotopes. One isotope, having mass 44 amu, is present in 16.1% abundance, while the other isotope, having mass 46 amu, accounts for the other 83.9%. What should be the experimentally deter- mined atomic weight for this hypothetical el- ement? Answer in units of amu
