To find the average atomic mass you must multiply all respective isotopic mass and its fractional abundance together and then add all the products.
Use the concentration and molar mass.
1.00 L (2.00 mol KCl/1 L)(74.6 g/ 1 mol KCl)= 149.2 grams
So, you need about 149 grams of KCl dissolved in 1 liter of water to prepare a 2.00 M solution.
It means the system absorbs energy from surrounding objects; usually, but not always, involving heat
The type of central-atom orbital hybridization corresponds to each electron-group arrangement
Linear
What is linear arrangement?
Linear molecules are molecules that are straight and have a bond angle of 180 degrees. These molecules are made up of a central atom that is bonded to two other atoms via single or double bonds (sometimes there can be triple bonds as well).
Furthermore, the central atom usually can have either 0 or 3 lone electron pairs (AX2 or AX2E3) in the AXE notation.
The geometry described by linear molecular geometry revolves around a central atom that is bonded to two other atoms (or ligands) at a bond angle of 180°.
