You need a in person tutor. Seriously, you are taking chemistry with not even close to having the math background needed. I recommend you discuss this with your parent.
this is standard fare in any AlgebraI class: https://www.montereyinstitute.org/courses/Algebra1/COURSE_TEXT_RESOURCE/U06_L2_T2_text_final.html
A SAMPLE OF ANTIMONY, Ar=121.8, WAS ANALYSED AND WAS FOUND TO CONSIST OF 60% OF 121Sb AND ONE OTHER ISOTOPE. DETERMINE THE MASS NUMBER OF THE OTHER ISOTOPE IN THE SAMPLE OF ANTIMONY.
Someone said:
assume you have 100 grams. It becomes the overused algebra candy mixture problem.
60*121+40*X=121.8*100
solve for x
Im really confused on:
-what the algebra candy mixture problem is and how it links to this
-why 121 was used and not 121.8
-What equation was used and must always be used for these sorts of questions
-What does x stand for
please help and explain clearly im stuck
