Explanation: It is slowly by wind or by water

Mass of limestone required for complete neutralization is 3,336.64 grams.

Limestone is . The neutralization reaction for limestone will be:

The balanced equation states that for neutralization of 1 mole of limestone, 2 moles and 1 mole of is required.

The moles of and available are:

Moles of = molarity volume (L)

Moles of = 8.9 15.5 L

Moles of = 13.975 moles

Moles of = 1.7   15.5 L

Moles of = 26.35   moles

Moles of required = 1 mole of + moles of

Moles of required = 26.35   moles + (13.975 moles)

Moles of required = 26.35   + 6.9875  

Moles of required = 33.3375   moles

Mass of limestone = moles of limestone molecular weight of limestone

Mass of limestone =  33.3375   moles 100.0869 grams

Mass of limestone = 3,336.64 grams.

 So the total moles of CaCO3 required is:

moles CaCO3 = 263,500 mol * 1 + 137,950 mol * (1/2)

moles CaCO3 = 332,475 mol

The molar mass of CaCO3 is 100.086 g/mol, so the mass is:

mass CaCO3 = 332,475 mol * 100.086 g/mol

mass CaCO3 = 33,276,092.85 g = 33.3 x 10^3 kg
