Question

Imagine two 2.0 g bags of protons, one at the earth's north pole and the other at the south pole. part a how many protons are in each bag?

Answer 1

Answer:
`1.19*10^(24)`

Mass of each proton
`= 1.67*10^-27 \hspace{1mm} kg`

Mass of protons in each bag = 2.0 g

Number of protons in each bag

`= \frac{Mass\hspace{1mm} of \hspace{1mm} protons \hspace{1mm} in \hspace{1mm} each \hspace{1mm} bag}{Mass \hspace{1mm} of \hspace{1mm} each \hspace{1mm} proton}\\ =(2*10^-3kg)/(1.67*10^(-27)kg)=1.19*10^(24)`
