A 1.130 g sample of limestone rock is pulverized and then treated with 30.00 mL of 1.035 M HCl solution. The excess acid then requires 11.56 mL of 1.010 M NaOH for neutralization.
Calculate the percent by mass of calcium carbonate in the rock, assuming that it is the only substance reacting with the HCl solution.
Express your answer using four significant figures.
