Answer: [tex] 1.19\times10^{24}[/tex]
Mass of each proton [tex]= 1.67\times10^-27 \hspace{1mm} kg[/tex]
Mass of protons in each bag = 2.0 g
Number of protons in each bag
[tex] = \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}\\ =\frac{2\times10^-3kg}{1.67\times10^{-27}kg}=1.19\times10^{24}[/tex]
