Students in science class were asked to do an experiment with a can of soda. They placed an unopened can of soda on a digital scale and recorded the initial mass as 340 g. They then opened the soda can and left it open for a day. The following day, the students took the mass of the soda can again and noticed that it was only 332g. They then poured some of the soda into a glass and observed that it was no longer fizzy.
