$V=3,5L\\
Cm=0,9M\\
M_{KCl}=74\frac{g}{mol}\\\\
C_{m}=\frac{n}{V}\\\\
n=\frac{m}{M}\\\\
C_{m}=\frac{m}{MV} \ \ \ \Rightarrow \ \ \ m=C_{m}MV\\\\
m=0,9\grac{mol}{L}*74\frac{g}{mol}*3,5L=233,1g$

B. Add 233 g of KCl to a 3.5 L container; then add enough water to dissolve the KCl and fill the container to the 3.5 L mark.

Gamma rays

Explanation:

Gamma rays is a form of electromagnetic radiation. It has zero mass and no charge.

Most radiations are particles but gamma rays are not particles they are mere rays.

They have an energy range between 10KeV and 3Mev
The range of gamma rays is not definite but it is very long.
The intensity of gamma rays for any medium decreases exponentially from the source.
Gamma rays are ionizing radiations
