An element X has the following isotopic compositionweighted average at

1.	An element X has the following isotopic compositionweighted average atomic mass of the elemena) 201 u41-90 %, 199X = 890 and 202. 2 %. Thet X is closest toc) 199 ub) 202 ud) 200 u
Answer» Answer:d)200uExplanation:The weighted Average atomic mass of element [x]=0.9(200)+0.08(199)+0.02(202)=180+15.92+4.04=199.96amu≈200 amu The weighted average atomic mass of the naturally occurring element X is closest to 200 amu

Answer:d)200uExplanation:The weighted Average atomic mass of element [x]=0.9(200)+0.08(199)+0.02(202)=180+15.92+4.04=199.96amu≈200 amu

The weighted average atomic mass of the naturally occurring element X is closest to 200 amu
