Malathion is pediculicidal (kills live lice) and partially ovicidal (kills some lice eggs). A second treatment is recommended if live lice still are present 7â9 days after treatment. Malathion is intended for use on persons 6 years of age and older.
Molar mass is computed as the sum of the masses of all elements in the compound considering one mole of that substance. The mass of Ca is 40.08 amu while the mass of I2 is 126.9 amu. In the equation, there are 1 unit of Ca and 2 units of I2. Thus, (1 Ca x 40.08 amu) + (2 I2 x 126.9 amu) is equal to 293.88 amu.
A mole of C 12 H 22 O 11 would have a mass of 342.299 grams.This quantity is known as the molar mass, a term that is often used in place of the terms atomic weight or molecular weight. The Mole. The term mole literally means a small mass. It is used as the bridge between chemistry on the atomic and macroscopic scale. If the mass of a single 12 C atom is 12.000 amu, then one mole of these atoms would have a mass of 12.000 grams. By definition, a a mole of any substance contains the same number of elementary particles as there are atoms in exactly 12 grams of the C isotope of carbon.
