Agraduated cylinder contains 15.75 ml of water. a metal that weighs 31.745 g is added. the final reading is 38.55 ml. using the correct number of significant figures, determine the density of the metal = g/ml first determine volume of metal: report result to the same number of decimal places as the number with the least number of decimal places. use this volume in calculation. second determine density of metal: d=m/v report result to the same number of significant figures as the number with the least number of significant figures. do not use exponential notation in answer.

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?

No copying 15 pts how does a free-body diagram tell you about the net force on an object?

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
