Answer 2

question : Out of 5.0 g and 5.00 g which one is more preferable and why ?

answer : 5.00 g is more preferable.

explanation : here first see significant figure of both of them.

5.00 g has three significant figure while 5.0 g has only two significant figure.

now your question must be , what does it mean ?

significant figure is related to accuracy. 5.0 g and 5.00 g both are same (if we exclude their significant figure) but their accuracy is different. 5.00g is more accurate than 5.0g because 5.00g will have lower error (±0.01) than 5.0 g (±0.1), if you want to find it.

now the number which is more accurate, must be more preferable.

Therefore 5.00g is more preferable value.
