True. To calculate the relative atomic mass of an element, you multiply the mass number of each isotope by its relative abundance (often expressed as a fraction or percentage) and then sum these products for all isotopes of the element. The final result is then typically divided by the total relative abundance to get the average (or weighted) atomic mass. So, this statement is correct.
True or false:
To calculate relative atomic mass, you multiply the mass number of the isotope with its % relative abundance
