Question

A. is wrong. What is the answer!?? Im so confused

Answer 1

Given:

a.

`60.0\text{ mg}`

b.

`0.354\text{ cm}`

To find:

a. mg into km

b. cm into nm

Step-by-step explanation:

a.

`\begin{gathered} 60.0\text{ mg} \\ =60.0*10^(-6)\text{ kg} \\ =6.0*10^(-5)\text{ kg} \\ =0.00006\text{ kg} \end{gathered}`

Hence,

`60.0\text{ mg=0.00006 kg}`

b.

`\begin{gathered} 0.354\text{ cm} \\ =0.354*10^(-2)\text{ m} \\ =0.354*10^7*10^(-9)\text{ m} \\ =3540000\text{ nm} \end{gathered}`

Hence,

`0.354\text{ cm=3540000 nm}`
