Stoichiometry CHEMISTRY A Stoichiometry can be thought of as the math of chemistry. It involves using relationships between reactants and/or products to determine such quantities as mass, moles, and number of atoms. Dimensional analysis is a way to simplify stoichiometric problem solving. In this activity, you will use dimensional analysis in order to count the number of atoms in a given substance. 1. A sample of gold (Au) has a mass of 35.12 g.   a. Calculate the number of moles of gold (Au) in the sample and record in Table 1. Show your work. 35.12au x (1mol/197g)=.18mol   b. Calculate the number of atoms of gold (Au) in the sample and record in Table 1. Show your work. .18mol x (6.022 x10^23 atoms/1 mol)= 1.08 x 10^23 atoms. 2. A sample of table sugar (sucrose, C12H22O11) has a mass of 1.202 g.   a. Calculate the number of moles of C12H22O11 contained in the sample and record in Table 1. Show your work. 1.202g (1mol sucrose)/(342g)=3.5 x 10^-3 mol sucrose.   b. Calculate the moles of each element in C12H22O11 and record in Table 1. Show your work.   .00296   c. Calculate the number of atoms of each type in C12H22O11 and record in Table 1. Show your work.    C= 7.2/3 x 10^22   H= 1.32 x 10^23   O= 6.62 x 10^22 Table 1 Au C12H22O11 Mass (grams) 35.12 g. Molar mass (g/mol) .18mol Moles of each element .00296 C: H: O: Atoms of each element C: H: O: Check answers and fill in chart

1 Imagine you and your team have been asked to give a presentation at a health care expo about consumers and their health care choices. To accomplish this presentation, your team has decided to select a health care company or product to use as an example during your presentation.Choose 1 of the following companies or products to use in your presentation:oHealth spa launching a new weight loss treatmentoInsurance company launching a new medical product for the exchangeoHospital system launching a new diabetes programoMedical device manufacturer launching a new metal alloy prosthesisoSelect your own company and product with approval from your instructorCreate a 12- to 15-slide presentation with speaker notes that includes the following: Section 1: General Company or Product InformationoDescribe the health care company or product.oDescribe the value of the services offered by your health care company or product. Section 2: Consumer InformationoAnalyze how consumers share health information through the company or the product.oAnalyze the implications of communication methods used when sharing health information. oConsider communication from physicians, pharmacies, and consumers when information is shared. Section 3: Impact of Outside AgenciesoAnalyze the impact government agencies have on services companies offer or products that are available to the health care consumer. Section 4: Impact of RegulationsoAnalyze the effect of health care reform on the health care consumer who uses the selected company or product. Section 5: Anticipating the Changing MarketoExplain how consumers’ options for health care are changing.oConsider if it will have an impact on the use of the company or product selected.oExplain how you will ensure the selected health care company or product will be relevant and engaging to the consumer over time.oDiscuss how advances in technology and medicine may influence the use of the company or product over time.Cite 3 peer-reviewed, scholarly, or similar references.Format your assignment according to APA guidelines, including a title and references slide and speaker notes.The section I’m needing completed is Section 4: Impact of RegulationsAnalyze the effect of health care reform on the health care consumer who uses the selected company or product.
