On the scantron form, bubble in the letter of the one choice that best completes the statement or answers the question. No credit will be given for multiple answers: lithium forms compounds which are used in dry cells and storage batteries and in high- temperature lubricants. It has two naturally occurring isotopes, 6li (isotopic mass = 6. 015121 amu) and 7li (isotopic mass = 7. 016003 amu). What is the percent abundance of lithium-6: 92. 50% 6. 080: what is the formula for lithium nitrite, lino2, li2no2, lino3, li2no3, lino4, potassium dichromate, k2cr2o7, is used in tanning leather, decorating porcelain, and water proofing fabrics. Calculate the number of chromium atoms in 78. 82 g of k2cr2o7: 9. 490 1025 cr atoms. Che 131 final exam, fall 2015, 47 questions total page 1: analysis of a carbohydrate showed that it consisted of 40. 0 % c, 6. 71 % h, and 53. 3 % Its molecular mass was found to be between 140 and 160 amu.
