What is the difference between the following ?
`(i)2.5xx10^(3)g and 2.50 xx10^(3)g (ii) 160 cm and 160.0 cm.`

Text Solution

Verified by Experts

(i) `2.5xx10^(3)` has two significant figures while `2.50xx10^(3)` has three significant figures. Hence, `2.50xx10^(3)` represents greater accuracy than `2.5xx10^(3)` . (ii) 160 has three significant figures while 160.0 has four significant figures. Hence, 160.0 represents greater accuracy.
