A compound that consists of 34.95% Carbon, 6.844% Hydrogen, 46.56% Oxygen, and 13.59% Nitrogen is found to have a molar mass of 315.28 grams / mole, what is the empirical and molecular formula for this compound?

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the answer is c i believe
