Calculate the number of C, H, and O atoms in 1.75 g of squaric acid

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 0.015mol of this acid.

Then we can easly calculate : 4 (0.015) = 0.06 mol for both for Carbon and Oxygen and 0.03 mol of Hydrogen.

To get more clear answer, we multiply by avogadros:

6.022 x 10^23. Hope everything is clear! regards
