Answer:
the electron cloud model is the current model of atom
As far as I remember, the needed formula for squaric acid is C4H2O4.
According to this one mole should be 114.06 g., which means we have <span>0.015mol of this acid.
Then we can easly calculate : </span><span>4(0.015) = 0.06 mol for both for Carbon and Oxygen and </span><span>0.03 mol of Hydrogen.
</span><span>To get more clear answer, we multiply by avogadros :
</span><span>6.022 x 10^23. Hope everything is clear! regards</span>
In 1 mole of 
, there are 3 moles of ions, 1 mole of Ca^{2+} and 2 mole of 
.
Molar mass of is 110.98 g/mol. Calculating number of moles from given mass as follows:
Thus, number of moles of ions will be 
.
Since, 1 mole of any substance has 
units of that substance where is Avogadro's number.
Thus, 9.38 mol of ions will have 
number of ions.
Therefore, total number of ions in 347 g of is 
.
