Why #355*g#.


Every chemical reaction conserves the component masses; of course such mass may be lost to the experimenter by evolution of gas or thru handling.

Here #355*g# of non-volatile material were used; and necessarily #355*g# of mass remain.

In another experiment a punter used the same quantities of material but used #300*g# carbonated water, i.e. fizzy water. After a few hours, the experimenter noticed a slight DROP in mass. How is this possible?
