<u>Answer:</u> The initial molarity of cation is 2.38 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

We are given:
Given mass of
= 46.3 g
Molar mass of
= 129.6 g/mol
Volume of solution = 150 mL
Putting values in above equation, we get:

1 mole of
produces 1 mole of
cation and 1 mole of
anion
So, molarity of
cation = (1 × 2.38) = 2.38 M
Hence, the initial molarity of cation is 2.38 M
B. The element nitrogen is made up only of nitrogen atoms.
Explanation:
Dalton stipulated , in his theory, that all the atoms of pure elements were identical. However different elements had different kinds of atoms that differ in their size and mass. The other stipulations of Dalton's theory were that atoms are the smallest unit of mass and were indivisible – this was later rebutted by advanced atomic theories .
Another major contribution by Dalton's theory is that chemical reactions involved the rearrangement of atoms observing the law of conservation of mass,
