Ok, We just started this in class and I have no idea how to do it.
When calcium carbonate reacts with hydrochloric acid, the products are carbon dioxide, water and calcium chloride. What volume of carbon dioxide at 785 torr and 27.0 degrees C is produced when an excess of calcium carbonate is added to 10.0 L of 0.158 M hydrochloric acid.
Any help would be appreciated!
