The weathering of four different rock samples with different masses was studied. Each rock sample was placed in a separate beaker containing 500 millimeters of a dilute acid for 10minutes. Bubbling was observed in some of the beakers. The data table below shows the mass of each sample, in grams, before placement in the acid and after removal from the acid.

limestone 19.72 19.64
granite 20.77 20.77
gneiss 26.83 26.83
marble 20.81 20.73
