The most precise reading of the mass of an object, among the following is a. 20 g b. 20.0 g c. 20.01 g d. 20 × 100 g
Added by Melissa K.
Step 1
20 g has a precision of 1 g (it could be anywhere between 19.5 g and 20.5 g) b. 20.0 g has a precision of 0.1 g (it could be anywhere between 19.95 g and 20.05 g) c. 20.01 g has a precision of 0.01 g (it could be anywhere between 20.005 g and 20.015 g) d. 20 × 100 Show more…
