Answer:
Explanation:
Metal elements form positively charged ions called cations because they are located on the left side of the periodic table These elements all have valence electrons in an s orbital. These electrons are relatively easy for the atom to lose to achieve a stable octet of electrons in its outermost energy shell.
Answer:
Molality = 1.13 m
Explanation:
Molality is defined as the moles of the solute present in 1 kilogram of the solvent.
Given that:
Mass of
= 26.5 g
Molar mass of
= 32.04 g/mol
The formula for the calculation of moles is shown below:
Thus,

Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )
So, molality is:

<u>Molality = 1.13 m</u>
