ANSWER
[tex]\begin{equation*} 2.45\text{ N} \end{equation*}[/tex]EXPLANATION
We want to find the weight of a 250-gram box of breakfast cereal in Newton.
To do this, apply the formula for weight:
[tex]W=mg[/tex]where m = mass in kilograms
g = acceleration due to gravity
Let us convert 250 grams to kilograms:
[tex]\begin{gathered} 250\text{ g}=\frac{250}{1000}\text{ kg} \\ \\ 250\text{ g}=0.25\text{ kg} \end{gathered}[/tex]Now, let us find the weight:
[tex]\begin{gathered} W=0.25*9.8 \\ \\ W=2.45\text{ N} \end{gathered}[/tex]That is the answer.
