Soda and lime are added to glass batch in the form of soda ash (Na2CO3) and limestone (CaCO3). During heating, these two ingredients decompose to give off carbon dioxide (CO2), the resulting products being soda and lime. Compute the weight of soda ash and limestone that must be added to 130 lbm of quartz (SiO2) to yield a glass of composition 72 wt% SiO2, 19 wt% Na2O, and 9 wt% Cao. Part 1 * Check your mathematics. You have the weight percent of these two constituents given in the problem, but you must convert them to the lbm of each so that you can eventually find the weight of both soda ash and time that should be added to the SiO2. You know the weight percent of both Na2O and CaO since that is given in the problem, and you are also given the weight of SiO2. Think back to the work you did in Chapter 4 and review your homework from that chapter. Think about what technique you can use to convert from weight percent to pounds (mass). If you are having difficulty with this problem, you may wish to review: Solving Equations Solving Simultaneous Equations You are to compute the weight (in Ibm) of soda ash and limestone that must be added to a certain amount of quartz to produce a particular glass composition. First, compute the lbm of both Na2O and Cao that is necessary for the particular glass composition that is given in the problem. What is the weight in lbm of: (a)Na20 0.3983 Ibm (b) Cao 0.2089 Ibm Part 2 What is the molecular weight in g/mol of the following: (a)Na2O g/mol (b) Na Coz g/mol (c) CaO g/mol (d) CaCO3 e g/mol Hint Attempts: 0 of 3 used Submit Answer Save for Later Using multiple attempts will impact your score. 5% score reduction after attempt 1 Part 3 Finally, convert the lbm of Na2O and Cao to the pounds (mass) of soda ash and lime that will need to be added to the SiO2. What is the weight, in lbm. of (a) soda ash and (b) lime that will be added to the SiO2 to make the glass outlined in the problem? (a) Ibm (b) 1 bm
