Answer:
universal mass unit
<h2 />
The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137 × 1023).
Answer:
Explanation:
1 Al = 26.98 AMU
3 Br = 239.7 AMU
AlBr3 = 266.69 AMU
Al = (26.98)/(266.69) = 10.1%
Br3 = (239.7)/(266.69) = 89.9%
