Show work for problems the require calculations. Calculations should have units and mightalso need labels.1. Calculate the mass in atomic mass units (AMU) of each of the following:o 1 O atom, with a mass of 2.66 x 10-23 gramso 1 Br atom, with a mass of 1.31 x 10-22 gramsSolution: One mole of an atom has a weight equal to the atomic mass expressed in grams.1 = 1.6605 1024 Therefore, the Mass in AMU of :o1 O atom, with a mass of 2.66 x 1023 g = 2.66 x 1023 g x1 amu1.6605 x 1024 g= 16.0189 amuo1 Br atom, with a mass of 1.31 x 1022 grams = 1.31 x 1022 g x1 amu1.6605 x 1024 g= 78.89 amu2. Calculate the mass in grams of 6.022 x 1023 atoms C atoms of mass 12.00 amu.SolutionMass of One atom of Carbon= 12.00 amu x1.6605 x 1024 g1 = 1.9926 x1023gramsatomHenceforth the mass in grams of 6.022 x 1023 atoms C atoms=1.9926 x1023gramsatom 6.022 x 1023 atoms = 11.999 grams3. Two parts of Dalton's theory had to be reworked due to scientific discoveries after histheory was published. One part was that atoms are indivisible and indestructible. Theother was that atoms of an element are identical. Describe in some detail, as provided bythe lecture and text, why these parts had to be reworked.Answer:The major drawback of John Dalton's theory is that he assumed that atoms were indivisible.The first revision happened in his atomic theory with the discovery of subatom ...
