Question

What is the percent composition of YAG (Yttrium Aluminum Garnet). The formula for

YAG is (Y3A15012).

Answer 1

Answer: Y 21.38 % , Al 32.44 % and O 46.16 %

Explanation: Molar mass of YAl5O12 is 88.91 + 5·26.98+12·16

= 415.81 g/mol

m-% ( Y) = 88.91 / 415.81 = 21.38 % , m-% (Al) = 5·26.98 / 415.81 =

32.44 % , rest is Oxygen
