a sample of dolomitic limestone containing only CaCO3 and MgCO3 was analyzed
a) when a 0.2800-gram sample of this limestone was decomposed by heating, 75.o milliliters of CO2 at 750. mm Hg and 20°C were evolved. How many grams of CO2 were produced?
b) write equations for the decomposition of both carbonates described above.
c) It was also determined that the initial sample contained 0.0448-gram of calcium. What percent of the limestone by mass was CaCO3?
d) How many grams of the magnesium-containing product were present in the sample in a. after it had been heated?
