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 170 lbm of quartz (SiO2) to yield a glass of composition 74 wt% SiO2, 19 wt% Na2O, and 7 wt% Cao.

You are to compute the weight (in lbm) 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. Na2O:
b. CaO:
