Tantalum (Ta) and boron (B) form two binary compounds with the following compositions: Compound Mass % Ta Mass % B 97.100 92.622 7.3777 (a) Compute the mass of tantalum that combines with 1.0000 g of boron in each case. grams Ta per gram B grams Ta per gram B 1 Compound 1: 33.478 Compound 2: 12.554 2.9004 (b) Show that these compounds satisfy the law of multiple proportions by giving the ratio of grams Ta per gram B in compound 1 to grams Ta per gram B in compound 2 expressed in terms of the smallest integers possible. Compound 1: grams Ta per gram B 33.47 Compound 2: grams Ta per gram B 2.554 If the second compound has the formula Tay84, what is the formula of the first compound? Use the smallest integers possible in your answer. Hint: you should not need atomic weights to solve this problem.
