Naphthalene has a very distinct odor, and it used to be the main ingredient in mothballs. It was discovered through the processing of coal tar. Naphthalene has the chemical formula C10H8. Answer and Explanation: The molar mass of naphthalene is 128.17052 g/mol. ...
Molar mass is the number of grams of a substance that equals one mole or6.02x1023molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted byg/mol. Answer and Explanation: KMnO4
The molecular mass is: 0.2720 g/4.500 × 10–3mol =60.44 g/mol You get 1 point for the correct number of moles of HA (or NaOH) and 1 point for the correct final answer. c.The approximate formula mass from the empirical (CH2O) formula is: 12 + 2(1) + 16 =30 g/mol ...
