Answer: the protons n neutrons
Explanation:
<h3><u>Answer;</u></h3>
= 0.6224 M
<h3><u>Explanation</u>;</h3>
Molarity is given by the formula;
Molarity = Number of moles/Volume
But moles = mass/Molar mass
Thus;
Moles = 12.47 g/80.043 g/mol
= 0.1556 Moles
Therefore;
Molarity = 0.1556 moles/0.25
<h3> <u>= 0.6224 M</u></h3>
