What mass $(kg)$ of calcium carbonate is required to react with sulfur dioxide that is

produced by burning $690kg$ of coal that contains $1\mathrm{.}0\%$ sulfur by mass $(k\frac{g}{k}g)?($see

page $113,$ Problem $3-10)($Hints$,$ find MW of Calcium carbonate, Sulfur, and sulfur

dioxide; find mass of sulfur, then mass of sulfur dioxide, then moles of sulfur dioxide,

then use stoichiometry of first equation on page $112$ to find moles of calcium

carbonate; find mass of calcium carbonate.
