[肝應化 10]

Window glass is typically made by mixing soda ash Na2CO3, limestone CaCO3, and silica sand SiO2 and then heating to 1500 degrees Celsius to drive CO2 from the Na2CO3 and CaCO3. The resultant glass consists of about 12% Na2O by mass, 13% CaO by mass, and 75% SiO2 by mass.

How much of each reactant (Na2CO3, CaCO3, SiO2) would you start with to prepare 0.38 kg of glass?

Why don't you solve this by yourself ?
