(10 pes) Nature conseil en mege mere (10 pts) NutraSweet, an artifical sweetner, is known to contain 57.14% C. 6.16% H. 9.52% 27.18% 0. Calculate the empirical formula of NutraSweet 10 150

Answer 1

Dale - Empirical formula let we have loog of sample, therefore mass of (2_57:149-,__=6:16 9_N29:529, 0:27:189- Atomic mass of (= 12.01 g/mol H=1.008 olmo N: 14.01gimo 10- 16.00 gimol Atom mass Atornic mass moter-atomicmass Relative molestan Reance C 54:14 120) =4.756 4.756 -3.0 14 0.6795 H 6.16 1.608 = 6:111 16.11! . 9.00 18 10.6795 9.52 14.0) -0.6795 10-6795 I atomicmass Relative molestiam mole no. = Rm x2 1 06795- 0 12918 | 16.00 -1.699 1.699 0.1455 = 22:505_ Therefore empirical formula of nutrasweet is, = TG4 H10 N₂O5 / Molecular Formula A molar mass of empirical formula 14x12.0) + 18 xlos +2x14.0L+ 5X16.00 = 94g mot If digits above were not rounded off than I molar man would have been 290 g/mol 1 Therefore, we will consider our empirical formula mass as 290. Ratio & mass - formula mass - 290 & 1 irical maxx 294 1. Molemular formula d swert is also, f Guts N₂O5 |
