You're on a roll — here are the answers to your questions: 1. The term mole is defined as the amount of substance that contains as many elementary entities (atoms, molecules, ions, or other particles) as there are atoms in exactly 12 grams of carbon-12. This number is Avogadro's constant. 2. Boyle's Law states that for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. Mathematically, this can be expressed as P_1V_1 = P_2V_2. 3. Two allotropes of Carbon are: Diamond* Graphite* (Other examples include fullerenes and graphene) 4. To calculate the number of moles in 440 g of CO_2: Step 1: Calculate the molar mass of CO_2. Given atomic mass of C = 12 and O = 16. Molar mass of CO_2 = (1 × 12) + (2 × 16) Molar mass of CO_2 = 12 + 32 Molar mass of CO_2 = 44 g/mol Step 2: Calculate the number of moles. Number of moles = MassMolar mass Number of moles = 440 g44 g/mol Number of moles = 10 mol The number of moles in 440 g of CO_2 is 10 mol. 5. A period in the periodic table is a horizontal row of elements. Elements within the same period have the same number of electron shells. 6. Avogadro's Constant is approximately 6.022 × 10^23 mol^-1. 7. The type of bonding that exists in Sodium Chloride (NaCl) is ionic bonding. Got more? Send 'em.
