Question

Which one of the following represents smallest quantity?

• A. $1850ng$
• B. $1.85\times 10^{-4}g$
• C. $1.85\times 10^3\mu g$
• D. $1.85\times 10^{-6}kg$

Answer 1

Answer: (A)

$1850g=1850\times 10^{-9}g=1.85\times 10^{-6}g$
$1.85\times 10^3\mu g=1.85\times 10^3\times 10^{-6}g=1.85\times 10^{-3}g$
$1.85\times 10^{-6}kg=1.85\times 10^{-6}\times 10^{3}g=1.85\times 10^{-3}g$
