##### Reference no: EM13121580

1.248-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.
