Document Summary
Calculate the mass of carbon in 125. 0 grams of aniline, c6h7n. This compound is the starting material for many dyes: a 1. 443 g sample of a metal is reacted with excess oxygen to yield 1. 683 g of the oxide. Calculate the atomic mass of the element m. % composition: when a 0. 761 g sample of a compound of c and h is burned in an combustion apparatus, 2. 23 g co2 and 1. 37 g h2o are produced. Empirical formula and molecular formula: an organic compound (0. 1014 g) which contains only carbon, hydrogen and oxygen, was combusted to give 0. 1486g of carbon dioxide and 0. 0609 g of water. Calculations based on equations: the solid fuel in the booster stage of the space shuttle is a mixture of ammonium perchlorate and aluminium powder, which react as follows: What mass of aluminium should be mixed with 5. 0 x 103 kg of ammonium perchlorate: camels store the fat tristearin (c57h110o6) in the hump.
