Question 116

During the synthesis of a novel semiconductor material, 0.62 g of element $D\text{D}$ is reacted completely with 0.80 g of element $E\text{E}$ to form a single compound.

Calculate the empirical formula of this compound.

(Relative atomic masses, $A_r$ : $D=31\text{D} = 31$ , $E=16\text{E} = 16$ )

You must show your working.
