Question

This is about scientific notation. Can someone plzzzz help I’m confused

Answer 1

Answer: Carat

Step-by-step explanation:

It is given that 1 atomic unit is equivalent to

$8.3\times 10^{-24}\ \text{carat}$ and $1.66\times 10^{-21}\ mg$

Express carat and milligram in the atomic mass unit, that is

$1\ \text{amu}\equiv 8.3\times 10^{-24}\ \text{carat}\\1\ \text{carat}\equiv \dfrac{1}{8.3\times 10^{-24}}=1.204\times 10^{23}\ amu$

For milligram

$1\ \text{amu}\equiv 1.66\times 10^{-21}\ mg\\1\ mg\equiv \dfrac{1}{1.66\times 10^{-21}}=6.02\times 10^{20}\ \text{amu}$

clearly, carat is greater than milligram
