To get the mass of a liquid sample, a student first measures the mass of an empty beaker on a precise balance: 100.1234 g. Student then pours the liquid såmple into the beaker and re-measures the mass, but this time he uses a less precise balance (because the first one was not available); the new mass (beaker + liquid) is: 123.4 g. What is the mass of the liquid sample?
a 23.3 g
b 23 g
c 23.28 g
d 23.2766 g
e 23.277 g
