Expert Answer
Given:
 
Weight of X = 0.36 g
 
Weight of xO = 0.56 g
 
0.36 space straight g space ofX space combines space with space 0.2 space straight g space of space oxygen o f space o x y g e n

Weight space of space straight X space react space with space 48 space straight g space space oxygen space is space fraction numerator 0.36 cross times 48 over denominator 0.2 end fraction

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 86.4 space straight g

Atomic space weight space of space straight X space equals space fraction numerator 86.4 over denominator 2 end fraction

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 43.2 space
