Question

2.05 pm to meters
express your answer to three significant figures and include the appropriate units.

Explanation:

Step1: Recall the conversion factor

1 pm (picometer) = $1\times10^{- 12}$ m.

Step2: Perform the conversion

$2.05$ pm = $2.05\times1\times10^{-12}$ m = $2.05\times10^{-12}$ m.

Step3: Express in three - significant figures

The number $2.05\times10^{-12}$ m already has three significant figures.

Answer:

$2.05\times10^{-12}$ m
