Is 5.00g is more precised than 5.0g?

Answer 1

5.0g and 5.00g are different because they contain different numbers of significant figures. 5.0 grams means that the measurement or value is correct within +- 0.1g. On the other hand, 5.00 means that the value is correct within +-0.01g.

5.00 is more accurate than 5.0, because it goes to the 100ths. Engineering wise you round up numbers to the 10ths

Answer 2

In science, decimal places are very important. 5.0 grams allows for a greater variance in measurement than 5.00. After all, 5.0 could be rounded from 5.0019 or 5.04213, which at an atomic level can mean quite a big difference.

Answer 3

yes - it is to 3 significant figures rather than two, therefore the error bounds are 5.00 +/- 0.005, which is obviously more precise than 5.0 +/- 0.05
