Quantitative chemistry

number of moles = mass/ molar mass

emperical formula:

n = relative mass of emperical formula/relative mass of compound

Avagadro's constant = 6.023 * 1023

Presure * Volume = number of moles* rate constant* temperature

Number of moles = volume/22.4(at stp) or 24 (at rtp)

concentration* volume = number of moles

Atomic Structure

protons and neutrons - in the nucleus

electrons - surrounding the nucleus

Protons charge is positive, neutrons is neutral and electrons is negative

protons mass is one, neutrons is one and electrons is 0

Mass number - mass of the atom - protons+neutrons

Atomic number - the positive charge of the nucleus

mass spectrometer - vopourization, ionization, acceleration, deflection and detection

Electron arrangement - spectra

electronic configuration and Ionization Eneger
