The molar concentration of the solution is calculated as follows
find the moles of NaCl used to make the solution
moles = mass/molar mass
mass =7.83 g
molar mass =58.5 g/mol
moles = 7.83 g/ 58.5 g/mol = 0.134 moles
molarity ( concentration in mol/l) = number of moles/volume in liters
volume in liters = 90ml/1000 =0.09 liters
molarity is therefore = 0.134 moles/0.09 L =1.49 M
X: 1S²2S²2P⁶
Y: 1S²2S²2P⁶3S²3P⁶
The statement which is most likely correct about the two elements is
They will not react because both have a complete outermost shell and are stable.
<u><em>Explanation</em></u>
The P orbital can hold a maximum of 6 electrons,therefore the 2P orbital for x and 3P orbital for Y which are outermost subshell are fully filled .
This make element Y and x stable since they cannot react either by gaining or losing electrons.
