Civil Engineering

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 carbondioxide (CO2), the resulting products being soda andlime. Compute the weight of soda ash and limestone that must beadded to 170 lbm of quartz (SiO2) to yield aglass of composition 78 wt% SiO2, 15 wt%Na2O, and 7 wt% CaO.

Part 1

You are to compute the weight (in lbm) of soda ashand limestone that must be added to a certain amount of quartz toproduce a particular glass composition.First, compute thelbm of both Na2O and CaO that is necessaryfor the particular glass composition that is given in theproblem.

What is the weight in lbm of:

(a) Na2O

lbm


(b) CaO

lbm

Part 2

What is the molecular weight in g/mol of the following:

(a) Na2O

g/mol


(b) Na2CO3

g/mol


(c) CaO

g/mol


(d) CaCO3

g/mol

Part 3

Finally, convert the lbm of Na2O and CaOto the pounds (mass) of soda ash and lime that will need to beadded 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 glassoutlined in the problem?

(a)lbm
(b)lbm
