Chem 219: Exam 3 Questions with Correct Solutions Avogadro's Law - Answer -equal volumes of gases at the same temperature and pressure contain equal numbers of molecules Boyle's Law - Answer -Boyle's Law states that at constant temperature and moles, pressure and volume are inversely proportional. Mathematically this is written as: PV = PV Charles' Law - Answer -the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperatur...

Chemistry A Level Edexcel 2023 Exam Questions And Complete Solutions Mass spectrometry - ANSWER using lasers to ionise atoms into cations, then measure the abundance and mass using their mass-to-charge ratios Mass to charge ratio - ANSWER the mass of an ion divided by its charge (usually +1 in mass spectrometry) units: m/z relative atomic mass - ANSWER the average mass of an atom of an element relative to 1/12 of an atom of the isotope C-12 relative isotopic mass - ANSW...

Avogadro's Law  equal volumes of gases at the same temperature and pressure contain equal numbers of molecules Boyle's Law  Boyle's Law states that at constant temperature and moles, pressure and volume are inversely proportional. Mathematically this is written as: PV = PV Charles' Law  the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of the gas increases and the volume of the gas decr...

Avogadro's number 6.022 x 10^23 atoms = 1 mole 1 u = ___ g 1.661 x 10 ^-24 g formula mass the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units. --The formula mass of a covalent compound is also called the molecular mass. The chemical identity of a substance is defined by the types and relative numbers of atoms composing its fundamental entities (molecules in the case of covalent compounds, ions in the case of ioni...

Avogadro's Number - Answer-6.02E23 amu in grams - Answer-1.66E-24 grams weight of a proton or neutron? - Answer-1 amu or 1.66E-24 grams Carbon-12 the most abundant isotope weighs exactly? (amu) - Answer-12 amu, it was the bench mark for amu. Difference between atomic mass and atomic weight? - Answer-Atomic mass is the amount of mass of a particular atom say carbon-12, or carbon-13. Atomic weight is the weighted average of all the isotopes of an element according to abundance. Ele...
