Question

difference between 5.0g and 5.00g​

Answer 1

Answer:

Though they look so be equivalent but scientifically they are different 5.0 g has two significant figures and hence its precision is 0.1 part in 5, i.e., 20 p.p.t. 5.00 has three significant figures and hence it precision is 0.01 parts in 5, i.e., 2 p.p.t. Hence, 5.00 g is more precise measurement than 5.0 g.

Answer 2

Though they look so be equivalent but scientifically they are different 5.0 g has two significant figures and hence its precision is 0.1 part in 5, i.e., 20 p.p.t. 5.00 has three significant figures and hence it precision is 0.01 parts in 5, i.e., 2 p.p.t. Hence, 5.00 g is more precise measurement than 5.0 g.
